What It Is
The SPEEDAIRE 4ZK98 is a filter regulator built for compressed-air systems that need clean, pressure-controlled supply. It combines a 40 micron particulate filter with a manual drain and an adjustable regulator in a single aluminum body rated for 250 psi maximum operating pressure. Industrial maintenance teams and pneumatic-equipment installers use it to protect downstream tools from contamination and pressure spikes.
Sustained Operation
At its rated 212 cfm maximum flow the unit maintains consistent filtration and pressure regulation across continuous duty cycles. The metal bowl with sight gauge lets operators monitor condensate level without interrupting airflow, while the manual drain allows scheduled purging during planned downtime. Reinforced nylon adjustment knob and top-mounted mechanism hold set pressure reliably under vibration and temperature swings typical in shop environments.
Deciding Specification
The 3/4 in NPT female inlet fixes the pipe size this regulator can accept without adapters. If your supply line uses a different thread size or gender, this unit will not connect directly. The left-to-right flow direction also determines mounting orientation in the airline.

Questions about this item
How much air can the 4ZK98 filter-regulator pass continuously?
The unit is rated for a maximum flow of 212 cfm at up to 250 psi operating pressure.
What size NPT fitting do I need on my supply line to connect the 3/4 in female inlet?
A 3/4 inch male NPT thread on the hose or pipe will mate directly with the regulator's female inlet.
Will the 40 micron particulate element protect my older pneumatic tools from fine debris?
The 40 micron filter traps particles at that size and larger, which covers typical rust scale and coarse contaminants in legacy systems.
