It uses a 40 micron particulate filter housed in a polycarbonate bowl with guard, with a durable aluminum body and a manual drain for straightforward maintenance. The 4ZK91A variant is listed as OEM Black NSMP, distinguishing it from other finishes, and features a top-mounted adjustment knob for precise pressure setting. Ideal for general shop air systems, it protects pneumatic tools, actuators, and spray equipment by removing particulates and stabilizing supply pressure, making it a common fit for bench tools and automotive or manufacturing setups that rely on clean, regulated compressed air. The unit’s 1\/2\" NPT inlet supports easy integration into standard air lines, and its 150 psi maximum operating pressure aligns with typical workshop compressors.\u003c\/p\u003e\u003c\/div\u003e","brand":"SPEEDAIRE","offers":[{"title":"New","offer_id":46259686179050,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/speedaire-4zk91a-pneumatic-pressure-filter-regulator","provider":"GTG Hardware","version":"1.0","type":"link"}
