SPEEDAIRE 4ZL99 Air Treatment Unit
The SPEEDAIRE 4ZL99 combines a filter, regulator and lubricator in one assembly for compressed-air systems. It handles a maximum flow of 160 cfm and an operating range of 5 to 150 psi with a 3/4 inch NPT female inlet. The 5 micron filter element and 32 oz metal bowls with sight glasses suit heavy-duty industrial use.
Sustained Operation at 160 cfm
The unit is rated for 250 psi maximum pressure while delivering up to 160 cfm continuously. A reinforced nylon adjustment knob on top sets outlet pressure across the full 5 to 150 psi range without creep during long runs. Metal bowls resist heat and chemical exposure better than polycarbonate alternatives in demanding environments.
Installation and Common Issues
Left-to-right flow direction and a 14 3/4 inch overall width determine mounting orientation and clearance. The 3/4 inch NPT female ports require matching male fittings and thread sealant. Manual drains must be opened regularly; forgetting this lets water and oil carry downstream into tools.

Questions about this item
How much air can the 4ZL99 pass continuously at its 150 psi working pressure?
The unit is rated for a maximum flow of 160 cfm, so it can supply that volume continuously when the regulator is set to 150 psi.
What size NPT fittings and thread sealant do I need to plumb this FRL into my shop air line?
The air inlet is a 3/4 inch female NPT port; you will need matching 3/4 inch male NPT fittings and suitable pipe thread sealant for a leak-free connection.
Will the 5-micron metal bowl and manual drain on this FRL work with my older compressor that puts out some oil and water?
Yes, the 5-micron metal bowl with sight glass traps particulates and the manual drain lets you purge accumulated oil and water from legacy compressors.
