Favorable price air FRL unit is a combination of filter, regulator and lubricator. It can filter the water, oil and other impurities in the compressed air, and keep the air source in a constant state to reduce the damage to valves or actuators of the device.

Features

• The structure of FRL unit is delicate and compact, which is convenient for installation and application.
• The pressed-in self-locking mechanism can prevent the abnormal movement of the set pressure caused by external interfere.
• The pressure loss is low and the efficiency of water separating is high.
• The quantity of oil dripping can be directly observed through transparent check dome.

Tips: Lubricator of FRL unit troubleshooting

No oil drips in the lubricator

• Improper use of oil type, use normal turbine oil for disassembly and cleaning wells.
• The oil passage is blocked by foreign matter such as dust, disassemble and clean the oil passage.
• The oil surface is not pressurized, disassemble and clean the air into the housing part.
• Due to poor oil quality and poor fluidity, replace with new oil after disassembly and cleaning.
• Because the surrounding temperature is too low, the viscosity of the oil increases, so that the surrounding temperature is increased to the applicable temperature.
• The oil volume adjustment screw is defective, remove the well to clean the oil volume adjustment screw.
• The air flow direction of the lubricator is reversed, and the installation direction is changed.

The oil in the lubricator cover has condensate mixed in

• Excessive accumulation of condensate in the filter housing flows into the lubricator, discharges the condensate and regularly discharges the water in the filter.

The lubricator leaks

• The gasket is not well sealed, replace the gasket.
• Synthetic resin housing is cracked, replace the housing.
• The dripping window is broken, replace the window.

The synthetic resin cover of the lubricator and the oil drip window are damaged

• Used in organic solvent gas environment, using metal housing and glass window.
• The influence of special additives in compressor lubricants, switch to other types of compressor lubricants.
• The air inhaled by the compressor contains substances that are harmful to resin, so replace it with a metal housing.
• Clean the housing and the dripping window with organic solvents, and replace the housing (use neutral detergent for cleaning).
