Why won't my Vanair Compressor build up full discharge?
- T
  Timothy LopezAug 4, 2025
  If your Vanair Compressor isn't reaching full discharge, several factors could be at play. First, the air demand might be too high; inspect service lines for any leaks or open valves. A dirty air filter can also restrict performance, so check its condition and replace it if needed. The pressure regulator could be misadjusted; refer to the Maintenance section for instructions on how to adjust it properly. If the regulator is defective, examine the diaphragm and replace it if necessary. Finally, ensure the compressor speed is correct and adjust it if it's not.

What to do if my Vanair ADHD Powertech Compressor shuts down with air demand present?

  If your Vanair Compressor shuts down while there's still air demand, it could be due to several reasons. The compressor discharge temperature switch might be open, indicating insufficient cooling air flow; clean the cooler and ensure proper ventilation. Check the fluid sump level and add fluid if it's low. A dirty compressor fluid filter can also cause shutdowns, so change the element. Ensure the electric fan is functioning correctly. A defective discharge temperature switch may also be the cause; check for a short or open circuit to the engine fuel solenoid. If the circuit checks out okay, the temperature switch itself might be defective. Lastly, check the instrument panel for a tripped circuit breaker and reset it, investigating the cause of the overload.

How to fix insufficient air delivery in my Vanair ADHD Powertech Compressor?
- D
  Doris WilsonAug 13, 2025
  If your Vanair Compressor isn't delivering enough air, start by checking the air filter; replace it if it's plugged. Also, inspect the air/fluid separator and replace the separator element if it's plugged, and change the compressor fluid and fluid filter. A defective pressure regulator can also cause this issue, so adjust or repair it as needed. Finally, make sure the engine speed is correct and readjust it if it's too low.

Why is my Vanair ADHD Powertech Compressor overheating?
- M
  markcooleyAug 19, 2025
  If your Vanair Compressor is overheating, several factors could be responsible. A dirty fluid cooler core or plugged fluid cooler tube (internal) can impede cooling, so clean them thoroughly. Check the sump fluid level and fill it if it's low. A plugged compressor fluid filter can also cause overheating, so change the element. Ensure the electric fan is functioning correctly by checking the wires, fan motor, and fan switch for faults, and replace any faulty parts.

What causes excessive fluid consumption in a Vanair ADHD Powertech Compressor?
- W
  Wanda GutierrezAug 25, 2025
  Excessive fluid consumption in your Vanair Compressor can stem from several issues. A clogged return line can cause this, so clear the orifice. Inspect the shutdown blowdown valve diaphragm and replace it if it's defective. Check the lubrication system for leaks in pipes, connections, and components. A damaged or improperly functioning separator element can also lead to high fluid consumption, so replace it. Finally, ensure the fluid sump isn't overfilled and drain it to the proper level if necessary.

What to do if Vanair ADHD Powertech has improper unloading with excessive pressure build-up?
- S
  Sonia MartinezAug 29, 2025
  Improper unloading in your Vanair Compressor, leading to excessive pressure build-up and the pressure relief valve opening, can be caused by several factors. If the pressure regulating valve is set too high, readjust it. A leak in the control system causing loss of pressure signal can also be the culprit, so check the control lines. Other potential causes include a defective pressure regulating valve (repair the valve), an inlet valve jammed (free or replace the valve), or a defective pressure relief valve (replace the pressure relief valve).
