Gardner Denver™’s solution for safely disposing of air compressor condensate
Traditional gravity type separators do very well in separating oils that have good separation characteristics. However, many compressor oils do not fully separate. These types of oils, known as emulsions, tend to foul-up the carbon filters as well as the pre-absorption and coalescing medias that are commonly installed in front of the carbon filters.

Note for Troubleshooter Filter Module

N/A A Troubleshooter filter module could last 12 months in a Rotary Screw application. However, filter life may be less due to lubricant, compressor type, and maintenance. Reduce cfm ratings by 50% for reciprocating compressors with lubricators.

When properly maintained, the troubleshooter will have discharge water containing less than 15 ppm of oil remaining.

Benefits and Savings

Benefits and Savings

  • Troubleshooter, is designed to effectively separate emulsified compressor condensate to levels of 15 ppm or less without premature element failure and backup spillages.
  • Delivery system, (patent pending) has pneumatically operated pump that is used to feed the filter module. The use of the pressure assures the filter will not clog.
  • Increased media's ability, up to four times the amount of oil that standard activated carbon can hold. This is due to the aluminosilicate is coated with hydrophobic compound (patent pending).
  • Improved efficiency, system only requires compressed air to operate the diaphragm pump.
  • Same delivery system is used for each filter module. Expanding air system may only require a larger filter module.



  • Separates Emulsified Oils
  • Low Maintenance Costs
  • Only Two Moving Parts
  • Fully Automatic
  • Non-Corrosive Materials
  • Extended Filter Life
  • Non-Clogging Filter Design
  • Effortless Maintenance Procedures



N/A The condensate enters the diffuser (1) chamber where it is depressurized. The oily condensate then enters a main reservoir (2) where gravity separation occurs. Any oil that floats to the surface is skimmed off through an adjustable oil weir (3). The condensate then moves to a separate chamber through a pick-up tube (4). As the condensate accumulates in the next chamber, a float (5) rises with the level of condensate. The float is connected to a ball valve (6) by a lever arm. The increased level of condensate causes the float to rise and open the ball valve. As the valve opens, the air-operated pump (7) is allowed to push the condensate out to the filter module (8). If the level of condensate continues to rise, the float also rises and further opens the ball valve. This results in additional condensate being pushed to the filter module. Thus, the system will self-adjust to the quantity of condensate entering the system. This system assures maximum contact time for the filter module.

The troubleshooter is the most economical and efficient way to separate emulsified, slowly demulsible, or high volume condensate loads. Determine the highest cfm flow possible with the application, then make your selection of the appropriate unit size.

Additional Information

Additional Information

N/A Those filters have to be replaced before their capacity is fully used. This is a result of oil binding off the pore area of the carbon where the condensate first comes in contact with the filter. The jelled oil clogs the filter, which then prevents the volume of condensate from properly flowing through the filter. This premature failure of the carbon filters most often results in the system backing up on the floor.

Inter-connecting fittings and hoses are supplied for connecting the delivery system to the filter modules.
