FAQ

∆P is for nitrogen pressure work on compatible shock absorbers and gas-charged suspension systems. It lets you carry regulated nitrogen pressure without bringing a full shop bottle to the vehicle, the track, the trail, or the job site. If pressure control matters where you work, ∆P is built for that moment.

We built ∆P for ourselves first. We needed better control of nitrogen pressure where the work actually happened, not only beside a full shop setup. Then we realized it was useful enough to become a real product for people who need the same control where they work, test, travel, race, or have fun.

That can mean an off-road owner, a racing team, a suspension shop, an aviation-adjacent operator, or a service tech. The common point is the same: they need controlled nitrogen pressure without depending on one fixed location.

The ∆P system includes the head, analog gauge, 24 in / 61 cm braided hose, and one pre-filled cartridge. The cartridge stores nitrogen at 1,740 PSI / 120 bar. The regulated output range is 0 to 725 PSI / 0 to 50 bar.

The cartridge stores nitrogen at up to 1,740 PSI / 120 bar. The regulated output range is 0 to 725 PSI / 0 to 50 bar. That matters because the goal is not only to carry pressure. The goal is to control the pressure before it reaches the shock or compatible system.

∆P is the portable system with one cartridge. ∆P Pro Components combines the ∆P system with the Charging Ramp, which lets users refill cartridges from their own nitrogen source.

If you only need portable nitrogen pressure, ∆P is the starting point. If you do repeated fills and already have a nitrogen supply, the Pro Components setup gives you the cleaner workflow.

The cartridge stores the nitrogen you carry with the ∆P head. The Charging Ramp is the hardware that fills cartridges from a nitrogen source.

One gives you portable capacity. The other gives you refill independence. A Charging Ramp is also the only hardware required to become a ∆P Official Partner.

You can use ∆P with systems that accept nitrogen and have a Schrader-type fill valve. Always follow the pressure recommendation from the shock or system manufacturer. If the system is not designed for nitrogen, or if you are guessing about the correct pressure, ask first.

It is the small valve many gas-charged shocks use for nitrogen service. It may look familiar because the valve format is common, but the job is very different from inflating a tire. In suspension, pressure changes how the shock behaves. Treat it like a technical setting.

∆P is for compatible nitrogen workflows. A hydraulic-only system without a nitrogen charge point is outside that use. If your system does not have a nitrogen fill valve or a manufacturer-approved nitrogen service procedure, ∆P is the wrong tool for that system.

Technically, yes, if you want to put nitrogen in a bike tire. It can be done, especially for a small adjustment. It is still clearly not the best use of ∆P. A normal bike pump or tire inflator is the right tool for normal tire work.

Technically, you can use ∆P to adjust pressure in very specific circumstances, but there is not enough nitrogen in a ∆P cartridge to fill a car tire from empty. A car tire is a much larger volume than a shock. Use tire equipment for tire work, and use ∆P where controlled nitrogen pressure is the point.

∆P uses nitrogen and is built around a specific pressure workflow. If the job accepts nitrogen and has the right Schrader-type valve, it may be compatible. If the job is a general inflation task, a compressor or inflator is the better tool.

Nitrogen is the standard gas for this kind of pressure work because it is dry, stable, and predictable. Compressed air can carry moisture and other variables we do not want inside a suspension pressure system. When pressure is part of how the system behaves, consistency matters.

The number of fills depends on your system volume and target pressure.

Use this formula: Number of fills = 54 ÷ (System volume in liters × Target pressure in bar).

For example, a 0.25 L shock charged to 5.5 bar is roughly the same as a 15.3 cu in shock charged to 80 PSI. That would allow approximately 39 fills.

Actual results may vary due to hose volume, connection loss, temperature, and remaining cartridge pressure.

For individual ∆P orders, yes. The system ships with one pre-filled cartridge. That is also why shipping has hazardous-material constraints. Pro Components and Charging Ramp users have a different workflow because they can refill cartridges from their own nitrogen source.

Yes, if you have a ∆P Charging Ramp and a proper nitrogen source. Individual users can buy a Charging Ramp. Official Partners use the same core refill hardware. Customers can also refill through Nimbus or an approved ∆P Official Partner.

The important point is the procedure. A cartridge should be refilled with the right hardware, the right gas, and the right pressure limit.

A welding shop may have nitrogen, but the cartridge should be refilled through the ∆P workflow. That means using a Charging Ramp, going through Nimbus, or going through an approved ∆P Official Partner.

If a local shop wants to offer this service properly, the clean path is to become an Official Partner. They only need the Charging Ramp to start.

The ∆P head still works, but the cartridge has no useful stored nitrogen left. You can refill it with a Charging Ramp, send it through Nimbus, or use an approved ∆P Official Partner.

The Delta P Charging Ramp is designed to prevent overfilling. If pressure rises above 120 bar (1,740 PSI), the ramp's purge valve automatically opens and releases excess pressure until the cartridge returns to its intended fill pressure.

Stop using the system until you understand the reading. A bad pressure reading can lead to a bad pressure decision. Send us a photo of the gauge, the cartridge, the connection, and the reading you expected. We would rather check it with you than have anyone guess with pressure.

You cannot fly with a filled ∆P cartridge. If the cartridge is empty, you can travel with it. Keep it fully empty and check the airline, airport, and local transport rules before you go, because pressure vessels are handled differently depending on the route.

Yes. The cartridge is designed with a safety margin well above its public operating pressure. Still, treat it like pressure equipment: keep it secured, avoid impact, and do not let it roll loose in a vehicle.

The Delta P cartridge is made from 6061 aluminum alloy, while the regulator head is made from brass. The cartridge is rated for 120 bar (1,740 PSI) operation and pressure tested to 300 bar (4,350 PSI). A durable dipped coating helps protect the exterior during normal use.

No. The cartridge is refillable and compatible with any ∆P head. That is the point of the system: carry a compact nitrogen source, use it, refill it through the correct path, and keep working.

Look at the cartridge, hose, fittings, gauge, and valve area before you connect anything. If something is bent, dented, loose, leaking, damaged, or strange, stop and contact Nimbus or an Official Partner.

Pressure work rewards calm habits. A short inspection is always worth it.

All ∆P products carry a 2-year warranty. The warranty covers defects in materials and workmanship under normal use.

Yes. The hose and gauge are covered by the 2-year warranty. Damage from misuse, accident, unauthorized repair, modification, or use against instructions is outside the warranty.

Contact Nimbus or the Official Partner who sold it to you within 72 hours. Send photos, order details, and your phone number so the right person can reach you quickly. If you bought through an Official Partner, their contact information will be on their listing or sales documents.

Any approved ∆P Official Partner can help you get the issue moving.

Because ∆P cartridges are hazardous-material products, change-of-mind returns are not accepted after delivery. If you need to cancel or correct an order before shipment, contact Nimbus as quickly as possible. Refund eligibility depends on order status and whether fulfillment or hazardous-material handling has started.

We ship ∆P worldwide through Nimbus and domestic representatives where available. Check the store locator to see whether ∆P is already available near you.

For the United States, we do not ship to Alaska, Hawaii, or US territories through the public checkout.

Pre-filled cartridges contain pressurized nitrogen. That makes shipping different from a normal box. Carriers need the right hazardous-material process, labeling, documentation, and handling. Local Official Partners help because a refill near the customer is easier than moving pressurized cartridges across long distances.

Use hello@nimbus-suspensions.com for order, warranty, and product support questions. Include the order email, photos when relevant, the product involved, and the pressure reading or symptom if the issue is technical.

Use appropriate safety equipment and follow the instructions for your shock, nitrogen source, and ∆P product. Follow manufacturer recommendations and local regulations for pressurized gases. If you are working with pressure, take it seriously.

A ∆P Official Partner is an approved business or operator that can support local cartridge refills, product access, and customer service. The partner becomes the local place customers can trust when they need nitrogen service, a replacement cartridge, a ∆P system, or help using the product correctly.

Good fits include off-road shops, suspension specialists, racing teams, aviation-adjacent operators, mobile service operators, industrial service providers, commercial door operators, and serious technical entrepreneurs.

We care more about competence and local fit than company size. A small operator with the right customers can be extremely useful.

A partner only needs the ∆P Charging Ramp to start. It costs $829 and gives the partner refill capability from their own nitrogen source.

Partners pay full price for the first unit of each product. After approval as an Official Partner, they receive partner discounts across the ∆P catalog.

No. The $1,678 ∆P Pro Components bundle is useful for professional workflows, but it is optional for partner onboarding. The partner path can start with the Charging Ramp and the monthly program membership.

The program fee is $179/month. Partners keep refill revenue and can build product sales around the refill relationship.

The refill is the repeat visit. The larger opportunity comes from product sales: ∆P systems, cartridges, Charging Ramps, and future accessories.

For partners with a physical store, it also creates useful foot traffic. A customer coming in for nitrogen service is already a customer with equipment where pressure matters. That is a good conversation to have in your own shop.

Partners set their own refill pricing based on their market. A shop in Dubai, Colorado, Belgium, or Yorkshire will not have the same costs or customer habits. We want partners to run the service in a way that makes sense locally.

Yes. Partners keep refill revenue.

Yes. Preferred ordering terms on eligible ∆P hardware are reserved for approved Official Partners. No one else receives those discounts.

Yes. Customers keep warranty validity when refilled by a ∆P Official Partner. That is one of the reasons the partner network matters: customers get a local refill point while staying inside the approved workflow.

Yes. Approved partners receive locator visibility, customer referrals when the location makes sense, and local Instagram and Facebook campaigns managed by Nimbus. We are also running ads to increase foot traffic at every partner location.

The goal is for customers to know where they can refill, buy, or get help before they need it urgently.

Yes, if they are serious about it. The investment is minimal for an entire line of business, and it can be done on the side or as a main activity.

For an engineering student, it can be a very good way to finance college years while building something real. The requirement is maturity. Pressure work needs careful people.

No. Every approved partner receives the same commercial structure regardless of size, market, or starting volume. Approval matters. Current volume does not.
