Unoair UH30 Single-Stage Air Compressor Pump, 3 HP, 13.8 CFM
The UH30 is Unoair's 3 HP single-stage twin-cylinder pump, the cast-iron workhorse under a long list of portable and light stationary compressors. It is the pump in the Unoair U2P2 twin-tank, the UH20 20 gallon horizontal and the UC5540H gas unit, so if you have an Unoair machine that still has good tanks and a good motor, this is how you keep it running instead of replacing it.
Key specifications
- Horsepower: 3 HP
- Delivery: 13.8 CFM
- Stages and cylinders: single stage, 2 cylinder
- Construction: cast iron
- Motor frame: suitable for 182 frame motors
- Weight: 53 lb
Where it fits
Unoair built this pump into the U2P2 10 gallon twin-tank (AirComParts U1015), the UH20 20 gallon horizontal (U1017, where it carries the UH-30-76A designation) and the UC5540H Honda gas twin (U1221). A 182 frame motor is the match for a direct swap. If your machine takes a 56 or 145 frame motor instead, you want the UH30D rather than this one.
Service notes
Cast iron and single stage means simple maintenance: oil level before every run, oil change on schedule, clean intake filter. Single-stage pumps live or die on intake air quality and on not being asked to hold 175 PSI, which is a two-stage job. Set the pressure switch to what the pump is rated for and it will outlast the machine around it.
Typical applications
Replacement pump for Unoair portable and light stationary compressors, shop-cart and job-site machines, farm and ranch units, and custom builds pairing a 182 frame motor with a 10 to 30 gallon receiver.
The Unoair UH30 single-stage air compressor pump delivers 13.8 CFM on 3 HP, in cast iron with two cylinders, for 182 frame motors.
