How to troubleshoot a DV Systems Air Compressor that won't start?
- M
  melissafryeAug 21, 2025
  If your DV Systems Air Compressor won't start, several factors could be at play. First, ensure the unit is receiving power by checking the disconnect or breaker and any fuses. Wiring connections should be tight and correctly placed according to the wiring schematic. Also, check if the Emergency Stop Button has been pressed; if so, release it. The motor overload might have tripped, requiring a reset. Overheating or over-pressure can also cause the compressor to stop; ensure sufficient airflow, appropriate ambient temperature, and a clean heat exchanger. Check the oil level and solenoid valve. Lastly, the unit may have timed out if the pressure hasn't dropped below 100 psi; in this case, lower the pressure and reset the unit. A power interruption could also be the cause; reset the unit.

Why is my DV Systems G20 consuming so much power?
- W
  William PopeAug 22, 2025
  High power consumption in your DV Systems Air Compressor can stem from several causes. Incorrect air pressure settings may be a factor; try resetting the pressure to the factory defaults. A malfunctioning blowdown solenoid could also be the culprit; inspect and replace it if necessary. Additionally, low voltage or a phase imbalance in your building's electrical system can lead to high power consumption, so it's advisable to contact an electrician for verification. Lastly, a failing motor can cause this issue; have the motor inspected.

What to do if my DV Systems Air Compressor is overheating?
- C
  Catherine LeonAug 25, 2025
  If your DV Systems Air Compressor is overheating, several factors could be responsible. High ambient temperature or blocked air circulation around the unit may be the cause. Ensure adequate cooling air circulation and inspect the air circulation around the unit. A dirty heat exchanger can also lead to overheating, so clean it. Check the oil level and add oil as required, or consider changing to the factory-recommended oil. A faulty thermo valve, a blocked oil filter, or a faulty temperature sensor or thermostat might also be the cause; check and repair or replace as necessary. High pressure can also cause overheating, so lower the pressure setting. Finally, make sure the cabinet door or panel is securely in place.

Why is there no or insufficient air flow from my DV Systems Air Compressor?
- L
  Leah CalderonAug 27, 2025
  If your DV Systems Air Compressor has no or insufficient airflow, start by checking the air filter; a dirty air filter can restrict airflow, so replace it. A blocked oil separator can also cause this issue, so replace the oil separator. A faulty intake valve or air leaks in the system might also be responsible; repair or replace the intake valve and check the unit and system for air leaks. Ensure that the pressure limits are correctly set. Additionally, check the wiring to the blowdown solenoid valve and replace it if necessary. Lastly, inspect the belts for proper tension and condition.

What causes high oil consumption in a DV Systems Air Compressor?
- C
  Claire MillerAug 28, 2025
  Excessive oil consumption in your DV Systems Air Compressor may be due to several reasons. The oil level might be too high, so reduce it to the proper level. A blocked oil return line (scavenge line) can also cause this issue; clean or replace the scavenge in-line filter. The oil separator could be saturated with oil, requiring replacement. Using the wrong type of oil can also lead to high consumption; switch to the factory-recommended oil. Check for any oil leaks and repair them. Lastly, ensure the unit is set to operate at correct pressures, with a minimum of 10 psi differential, and consider if the unit is oversized for the tank capacity.

Why is my DV Systems G20 surging?
- H
  Heather DiazAug 30, 2025
  Compressor surges in your DV Systems Air Compressor can be attributed to several factors. A restriction in the heat exchanger or hoses may be the cause; flush out or replace them. The pressure transducer setting might be incorrect or malfunctioning; set the pressure as per instructions or replace it. Check for any blockages at the unit outlet. Additionally, the dryer might be freezing up, preventing air from passing through; check that the dryer parameters are correct and increase the dew point to 2.0 if required. Finally, an undersized air receiver can also lead to surges; use a minimum 120 Gallon Tank.

What do fault alarms on my DV Systems Air Compressor mean?
- K
  katrina57Sep 1, 2025
  Fault alarms on your DV Systems Air Compressor can indicate several issues. First, check that the Emergency Stop Button is not pressed in. High temperature can trigger an alarm. Low ambient temperature can also cause alarms; increase the ambient temperature to 10°C. High pressure can also trigger alarms; check the pressure settings, the Pressure Transducer, and the wiring to the Transducer.

Why does my DV Systems G20 Air Compressor start slowly?
- A
  Amy GarrettSep 2, 2025
  A slow-starting DV Systems Air Compressor could be due to a few reasons. The intake valve may not be functioning properly, so check its operation and repair or replace it as needed. Low ambient temperature can also cause slow starts; try stopping and restarting the compressor once the ambient temperature increases. A minimum pressure valve leaking back to the air end or set too high can also be responsible; repair or replace the minimum pressure valve or adjust its setting to 65 psi. Finally, using the wrong type of oil can contribute to slow starts; change to the factory-recommended oil.

What to do if the intake valve leaks oil when my DV Systems G20 stops?
- M
  Melissa NelsonSep 4, 2025
  If the intake valve of your DV Systems Air Compressor leaks oil when the unit stops, it could be due to a few reasons. The intake valve seal might be leaking, so repair it using an intake valve repair kit. Alternatively, the intake valve might be stuck in the open position, requiring repair or replacement. Lastly, a non-functioning blowdown solenoid could be the cause, so replace the solenoid.

How to fix no or insufficient airflow in my DV Systems Air Compressor?
- K
  kyle75Sep 10, 2025
  If your DV Systems Air Compressor has no or insufficient airflow, the following issues could be the cause: * A dirty Air Filter. * A blocked Oil Separator. * A faulty Intake Valve. * Air leaks in the system. * Incorrectly set pressure limits. * An open Blowdown Solenoid Valve. * Broken or slipping Belts. To resolve this, replace the Air Filter, replace the Oil Separator, repair or replace the Intake Valve, check the unit and system for air leaks, adjust the pressure settings, check the wiring to the Solenoid and replace as necessary, and check the Belt tension and condition.
