Expert Advice

Mark Allen says

This is a petrol-driven, belt‑drive workshop compressor intended for sites where you cannot rely on a mains electrical supply. In practice it suits mobile bodyshop work, farm and fleet maintenance, or any outdoor repair where you still need proper air delivery for tools and inflation.

In real use, it will typically run ½" drive impact wrenches, air chisels, blow guns and, with sensible duty cycles, smaller spray jobs or panel preparation tools. The 150 litre receiver gives a decent buffer so the engine isn’t hunting on and off every few seconds.

Two key considerations: first, ventilation and exhaust – a petrol unit must be run outside or in a very well‑ventilated area, never in a closed booth. Second, match the free air delivery to your tool demand; continuous high‑draw tools like DA sanders will quickly show up any shortfall.

A common issue is poor maintenance of filters, oil and drive belts, which shortens pump life and causes overheating. Treated properly, these Workhorse petrol compressors are reliable on-site units, provided they’re sized correctly and maintained to workshop standards.

FAQs

What air output and engine does the Workhorse petrol air compressor 11hp 150l provide, and is it suitable for workshop use?

This unit uses a Honda GX 11 hp petrol engine driving a twin‑cylinder, belt‑driven cast iron pump with a displacement of around 29.8 CFM and a free air delivery of about 23 CFM at up to 10 bar (145 psi). That output is more than adequate for typical mobile bodyshop and workshop tasks such as impact guns, spray guns, smaller blast pots and general air tools, provided the tools are matched to the 23 CFM FAD and the duty cycle is managed properly.

Is the 150 litre Workhorse petrol compressor genuinely mobile, and what power supply does it need?

Being petrol driven with a 150 litre static receiver, this compressor is designed for use where there is no mains power available – for example mobile repair work, remote farm or construction sites, or outside bodyshop bays. There is no electrical supply requirement for the compressor itself beyond the electric start battery where fitted, so you do not need a 230 V or 400 V supply. You do, however, need clear access for moving the unit with a pallet truck or similar as it weighs around 160 kg.

What applications is this compressor suited to in a professional bodyshop or workshop?

The air output and 10 bar working pressure make it suitable for most mobile bodyshop and workshop tasks: panel beating tools, ½ inch impact wrenches, DA sanders (used sensibly), sealant and caulking guns, tyre inflation and light to medium spray work. For continuous high‑demand tools such as large blast pots or multiple users on DA sanders, we would normally recommend either a larger fixed electric compressor or careful planning of air usage so the pump and receiver are not run flat out all day.

What maintenance and support should we plan for with this Workhorse petrol compressor?

As with any petrol, belt‑driven compressor, you will need regular checks on engine oil, compressor oil, belt tension, intake filters and drain down of the 150 litre receiver to remove condensate. The Honda GX engine is a proven industrial unit with widely available service parts, and the cast iron pump is designed for long life at slow running speeds if serviced on schedule. BWS can support you with advising correct installation, routine servicing, genuine parts and on‑site repair if required, which is important if the compressor is a primary air source for mobile work.
