Vanair Air Compressors & Mobile Power Systems
Vanair builds air power onto the truck: Viper gas and diesel rotary-screw compressors, Reliant and ADHD compressors that run off your chassis hydraulics, Air N Arc all-in-one air, welder, generator and battery power systems, and PRO Series reciprocating compressors. Crowder Supply stocks the line with live prices, factory specs and OEM parts support.
The short version
Air on the truck without towing a compressor. Gas engine and no hydraulics: the Viper Gas G80 (80 CFM, from $10,666) or G60 (150 PSI) puts rotary-screw air in a 440 lb package. Diesel fleet: the Viper Diesel D60–D80. Truck already has PTO hydraulics: a Reliant RC40 ($7,126) makes 30–40 CFM with no second engine. Need to weld too: the Air N Arc 150 ($12,004) is air, welder, generator and battery power in one frame. Budget reciprocating air: the PRO 35 ($4,699). Compare every brand in gas-driven and diesel-driven air compressors, read the Air Compressor Buyer’s Guide, or call 1-888-883-5144.
Viper Gas Rotary-Screw Compressors
60–80 CFM of continuous rotary-screw air from a 25 HP Honda — half the weight and footprint of a tow-behind, with a lifetime warranty on the encapsulated airend. See the Air Compressor Buyer’s Guide for sizing.
The Viper Gas platform
One 440 lb deck-mount platform, 39 x 21 x 30 in., three stocked outputs: the airend is sized to trade pressure for volume, so you pick the model by the tools you run. 25 HP Honda iGX800 EFI, 10-gal fuel tank, cold weather, remote start and DOT wheel cart options on every model.
Vanair Viper Gas G80
The volume pick: 80 CFM at 100 PSI feeds air-hungry work — sand blasting, 4-in. piercing tools, or a small crew of pneumatic tools off one machine. Stocked with the 25 HP Honda, plus a Kohler-engine unit currently on sale.
Choose it when you want the most air the platform makes and your tools live at 90–100 PSI.
Key specs
Vanair Viper Gas G60
The pressure pick: 60 CFM at a full 150 PSI for tools that want pressure over volume — 90 lb breakers, post drivers, rock drills and long hose runs. Also the right envelope for irrigation blow-out work.
Choose it when your tools need 150 PSI at the coupler, not just CFM on the plate.
Key specs
Vanair Viper Gas G70
The middle path: 70 CFM at 125 PSI covers mid-size pneumatics and mixed toolboxes when the G60’s airflow runs short and the G80’s 100 PSI is not enough pressure.
Choose it when your day mixes breakers, drills and air tools and no single spec dominates.
Key specs
Viper Diesel Rotary-Screw Compressors
The same 60–80 CFM airend on a 24.8 HP Kubota Tier 4 Final diesel — direct drive with no belts, automatic variable speed, and factory muscle to run a 90 lb jackhammer.
The Viper Diesel platform
Deck-mount 735 lb package, 48 x 21 x 33 in., with a 9-gal fuel tank, 60 A alternator and integrated battery. Auto shut-off and variable speed cut fuel burn; high-temp, low-oil and overpressure shutdowns protect the machine. Lifetime warranty on the encapsulated airend.
Vanair Viper Diesel D60
60 CFM at a full 150 PSI on diesel — the pressure pick for breakers, post drivers and rock drills running off a diesel service truck.
Choose it when the fleet runs diesel and your tools need 150 PSI all day.
Key specs
Vanair Viper Diesel D70
70 CFM at 125 PSI — factory-rated 100 PSI at altitudes above 3,500 ft, and stocked here in the high-altitude configuration with fuel tank and pump.
Choose it when you work at elevation or run a mixed toolbox off a diesel deck.
Key specs
Vanair Viper Diesel D80
The diesel volume pick: 80 CFM at 100 PSI, holding 48 CFM even at idle. Feeds blasting, piercing tools and multi-tool spreads off one deck-mount machine.
Choose it when airflow is the spec that matters and the truck is diesel.
Key specs
Reliant & ADHD Hydraulic-Drive Compressors
Run air off the hydraulic system your truck already has — no second engine, no extra fuel system, from a 195 lb rotary screw to a 185 CFM jackhammer-class machine.
Abovedeck hydraulic drive, 30–185 CFM
The Reliant series (RC40, RC40-L, RS45, RS85-L) and the high-CFM ADHD run entirely off chassis hydraulics — crane trucks, service bodies and mechanics trucks with spare GPM get compressed air with nothing extra to fuel or maintain. Open- and closed-center systems are both supported, with cold weather packages available across the line.
Vanair Reliant RC40 — Open Center with Cold Weather Package
Two-stage cast-iron reciprocating compressor, belt drive, making 30–40 CFM at up to 175 PSI from 9.5–12 GPM of hydraulic flow. The stocked unit is the open-center build with the factory cold weather package and hydraulic thermal valve.
Choose it when your crane or service truck has 10–12 GPM to spare and you want proven cast-iron durability.
Key specs
Air N Arc All-in-One Power Systems
Air compressor, DC welder, AC generator, battery boost and battery charge in one service-body footprint — five forms of power, one machine to mount and maintain.
The Air N Arc line
From the 20 CFM Air N Arc 150 to the 330 Diesel with its Lincoln Electric 330 A multi-process welder and 10 kW generator, every Air N Arc replaces a compressor, a welder, a generator and a jump box with one unit. Vanair is a Lincoln Electric company, and the PowerFlex variants supply air, electric and hydraulic power without the welder where that fits the truck better.
Vanair Air N Arc 150 — 20 HP, 30-Gal Air, 11.5-Gal Fuel
The stocked all-in-one: 20 CFM reciprocating air, 40–150 A DC welder, 5 kW generator, 150 A battery boost and 50 A charge, powered by the 20 HP Vanair VNR680 V-twin with electric start.
Choose it when one body compartment has to carry your compressor, welder, generator and jump pack.
Key specs
PRO Series & Contractor Reciprocating Compressors
Honest reciprocating air at the lowest cost of entry — mechanics, ag and service work that needs a reliable 25–35 CFM without rotary-screw money.
Vanair PRO 35 — 30-Gal Receiver, Honda Electric Start
35 CFM reciprocating compressor rated to 175 PSI max on a 30-gallon receiver, with Honda power and electric start. The economical way to put real air on a truck.
Choose it when the budget says reciprocating and the work is intermittent — tires, service calls, ag repairs.
Key specs
Utility Mount 185–260 CFM Systems
Tow-behind-class airflow mounted on the truck: Tier 4 Final diesel systems for utility fleets that live on air.

What does Vanair make?
Vanair builds vehicle-mounted mobile power: Viper gas and diesel rotary-screw air compressors, Reliant and ADHD hydraulically driven compressors, Air N Arc all-in-one air/welder/generator/battery systems, PRO Series and Contractor reciprocating compressors, and Utility Mount 185–260 CFM systems. The idea across the whole line is the same — put the compressor on the truck instead of behind it.
Who owns Vanair?
Vanair Manufacturing is a Lincoln Electric company. Current factory literature is published jointly with Lincoln Electric, and the Air N Arc 330’s 330 A multi-process welder is a Lincoln Electric unit built on Lincoln’s Chopper Technology.
Should I buy the Viper Gas or the Viper Diesel?
The airend and outputs are the same — 60, 70 or 80 CFM. The Viper Gas runs a 25 HP Honda iGX800 EFI, weighs 440 lb and starts at $12,999. The Viper Diesel runs a 24.8 HP Kubota Tier 4 Final, weighs 735 lb, starts at $18,856 and adds automatic variable speed and shutdown protection. If the truck and the fleet are diesel and the machine works daily, buy diesel; for lighter chassis and intermittent use, the gas Viper saves real money up front.
Can a Vanair compressor run a 90 lb jackhammer?
Yes. Vanair factory-rates the Viper Diesel and the ADHD hydraulic compressor for 90 lb jackhammers, and the 60–80 CFM Viper Gas models cover 60–90 lb class breakers, piercing tools and post drivers — one big tool per machine.
What hydraulic supply does a Reliant need?
The RC40 needs 9.5 GPM (30 CFM) to 12 GPM (40 CFM) at 1,775–2,275 PSI; the aluminum RC40-L needs 8.25–10 GPM at 2,300–2,600 PSI; the RS45 runs on as little as 7 GPM. Vanair’s ratings assume 120°F hydraulic fluid — add a minimum of 400 PSI for continuous ratings. Open-center and closed-center systems are both supported.
What is an Air N Arc?
An Air N Arc is Vanair’s all-in-one power system: an air compressor, DC welder, AC generator, battery booster and battery charger sharing one engine and one frame. The I-300 adds a hydraulic pump for crane work — six forms of power — and the 330 Diesel pairs a Lincoln Electric 330 A multi-process welder with a 10 kW generator.
Do Vanair compressors work at high altitude?
Yes, with the right configuration. Vanair’s guidance is that engine power falls about 3.5% per 1,000 ft of elevation; the Viper D70 is factory-rated 100 PSI above 3,500 ft, and we stock high-altitude Viper configurations — look for the high-altitude option on the PDP or call us with your elevation.
Does Crowder Supply stock Vanair parts?
Yes. OEM Vanair parts are listed by part number in our parts catalog — panels, filters, control modules, harnesses, service kits and Vanguard compressor oils — and exploded parts diagrams and operations manuals for the Viper, Reliant and Air N Arc lines are on the site.
Which Vanair models does Crowder Supply stock?
Stocked with live pricing today: Viper Gas G60/G70/G80, Viper Diesel D60/D70/D80, the Air N Arc 150 20 HP, the Reliant RC40 open-center with cold weather package, the PRO 35, and the accessory range.

How fast do Vanair machines ship?
Stocked models ship within one business day; the rest ship within a few business days. We ship nationwide from our own stock and, on some lines, direct from the manufacturer, so transit depends on the item rather than one warehouse — freight is quoted alongside the machine.
