Frequently Asked Questions about Towable Air Compressors

What is a 185 CFM air compressor used for?

A 185 CFM air compressor is commonly used for construction, rental, demolition, utility work, road repair, sandblasting, pneumatic tools, and general jobsite compressed air. It is a popular portable compressor size because it supports many common field applications.

What is the difference between a 185 CFM and 195 CFM portable air compressor?

The main difference is air capacity. A 195 CFM portable air compressor provides slightly more air flow than a 185 CFM unit. The right choice depends on your tools, pressure requirements, number of air users, and jobsite conditions.

Is a 185 CFM air compressor good for sandblasting?

A 185 CFM diesel air compressor can be used for some sandblasting and abrasive blasting applications, depending on nozzle size, pressure requirements, blasting media, and duty cycle. Kaeser can help determine whether a 185 or 195 CFM compressor is right for your blasting setup.

What is a tow-behind air compressor?

A tow-behind air compressor is a portable compressor mounted on a trailer or towable frame so it can be transported between jobsites. Tow-behind compressors are commonly used in construction, demolition, road work, utility work, sandblasting, and rental applications.

Are 185 CFM portable air compressors diesel-powered?

Many 185 CFM portable air compressors are diesel-powered because they are designed for jobsites where electric power may not be available. Diesel portable compressors provide independent compressed air for field and construction applications.

Can a portable air compressor be used as backup for a stationary compressor?

Yes. A portable air compressor can be used as temporary backup air during stationary compressor maintenance, repair, outage, or system upgrades. Kaeser can help determine whether a 185 or 195 CFM portable compressor can meet your temporary air requirements.

How do I choose the right towable air compressor?

To choose the right towable air compressor, consider required CFM, operating pressure, tools or equipment being used, number of air users, duty cycle, jobsite conditions, fuel needs, and service support. Kaeser can help recommend the right compressor based on your application.
