Air filter regulator for compressed-air systems
The SPEEDAIRE 4ZK99 filter regulator combines a 40 micron particulate filter with a pressure regulator in a single aluminum body. It accepts a 3/4 inch NPT female inlet and delivers a maximum flow of 212 cfm at up to 150 psi. Overall dimensions are 11.93 inches high and 3.15 inches wide, with a polycarbonate bowl protected by a guard and a manual drain. A top-mounted reinforced nylon knob adjusts outlet pressure and flow direction runs left to right. No pressure gauge is included.
Suits workshops needing clean regulated air
This unit fits pneumatic lines that require particle removal down to 40 micron and consistent downstream pressure up to 150 psi. It is not intended for applications needing oil removal, automatic drainage or an integrated pressure gauge. Builders who need a finer filter rating, a different port size or a gauge on the body should look at other configurations.
Mounts inline in a compressed-air circuit
Install the regulator between the compressor or main header and the point of use, using the 3/4 inch NPT female threads. The left-to-right flow orientation must be observed. The manual drain requires periodic operator attention to empty collected moisture. The compact width leaves space for adjacent fittings or a separate gauge tee, while the aluminum body withstands typical shop environments.

Questions about this item
What size NPT fitting do I need on my air line to connect to the 3/4 in inlet?
The filter-regulator has a 3/4 in female NPT air inlet, so your supply line must terminate in a matching 3/4 in male NPT thread.
Will the 212 cfm maximum flow rate restrict my existing 1/2 in distribution piping?
At 212 cfm the unit can pass more air than typical 1/2 in piping delivers, so the piping — not the regulator — will likely be the bottleneck.
How can I confirm the regulator is holding pressure after I set the knob?
No pressure gauge is included, so you must install a separate gauge downstream or at the point of use to verify the set pressure.
