When a towable compressor goes down, the whole crew waits. Innovative Oil Solutions repairs, maintains and supplies parts for diesel portable air compressors, from 185 CFM utility units to high-pressure machines that run blasting, drilling and pipeline work. One call. We take it from there.

A diesel portable compressor is really two machines working together: a diesel engine and a rotary screw air end. Most shops are strong on one and guess on the other. Our technicians work on compressed air every day, and they service the engine, the air end, the controls and the trailer as one system, so a fix on one side does not cause a failure on the other.
We bring the same discipline we use on plant air systems to portable units: service by the hour meter, the right fluids and filters, and a full load test before the unit goes back to work. Need a new machine instead? We provide sales, service and support for the ELGi portable compressor line.
Oil, fuel and air filters, fuel system checks, belts, hoses, batteries, starting and charging problems, and diagnosis of shutdowns and fault codes.
Compressor fluid, separator elements, inlet valves, minimum pressure valves, thermostatic valves, couplings and air end troubleshooting when the unit will not build or hold pressure.
Controllers, gauges, sensors, regulators and dual-pressure settings, so the unit loads and unloads cleanly at the pressure your tools need.
Radiator and oil cooler cleaning, thermostatic valve service and fan and belt checks. Texas heat and dust are hard on portable coolers.
Aftercoolers, water separators and filtration for coatings, blasting and other work that needs cooler, drier air at the hose.
Hitch, safety chains, lights, tires and wheel hardware, plus leak and guard checks before the unit goes back on the road.

Most portable failures we see trace back to the same few causes: overdue filters and fluids, clogged coolers, fuel problems and units that sat too long between jobs. A simple routine prevents most of them:
