MicroAir
On Line Controls' MicroAir products have a life span of 10 – 20 years. Any air pressure unit less than 10 years old can be serviced quickly usually in one day. Older units can be sent in for evaluation. If you are having problems with your MicroAir regulator, we suggest the following steps:
Check that unit is:
1. Mounted securely in a vertical position.
2. Input and output connections are not damaged.
3. Check that the input air is approximately 35 psi – 45 psi. MultiAir units require more air 50 – 60 psi.
4. Oil cup is approximately ¾ full.
5. Check that Flow Valve is open (Counter Clockwise) (1 turn for 2-10”, 2-3 turns for 15-30”, 3-4 turns for 3 psi and 4-6 turns for 5 psi). Air volume adjustment is described further in your users manual.
6. Disconnect controlling electrical connections to the terminal strip (motorized units only) and retest unit.
7. If you are having problems with our Dual or MultiAir 3-channel or 4 channel units, please call customer service for additional help.
8. If none of these steps correct your problem, please return the unit for repair – See return instructions below.
Note: If returning a MicroAir please EMPTY OIL DAMPING CUP. A clean up charge will be added to the repair, if unit is shipped with oil. Replacement oil will be supplied with repaired unit.
Motorized Potentiometers
Motorized Potentiometers built by On Line Controls, Inc. can be returned for repair or rebuilding. Delivery will depend upon available parts. Our service department will also try and repair older (OEM) ETI motorized potentiometers (MC, MAC, ME series) built in the 80’s and 90’s. The clutch on your motorpot has been factory set. Any adjustments will make the unit inoperable and void the warranty.
Returning for Repair
1. Pack in box with sufficient packing material so no damage will result in shipping.
2. Include a brief description of the problem and a name and phone number of person to contact if we have any questions, and a return ship to address.
3. Ship to:
