Suitable for both domestic compressors and light industrial applications, this device integrates easily into any existing pneumatic system. The wide adjustment range (2–12 bar) and robust metal construction make it a reliable long-term solution.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-benefits\"\u003e\n\n\u003ch2\u003eWhat you get with this product\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eAutomatic compressor start and stop — no more need to manually monitor tank pressure\u003c\/li\u003e\n\n\u003cli\u003e4 independent NO\/NC outputs — you can connect multiple circuits or auxiliary equipment simultaneously without additional parts\u003c\/li\u003e\n\n\u003cli\u003eFlexible adjustment between 2 and 12 bar — compatible with most single-phase compressors on the market\u003c\/li\u003e\n\n\u003cli\u003e16A at 230V AC electrical contacts — supports standard compressor motors without risk of contact overload\u003c\/li\u003e\n\n\u003cli\u003e1\/4\" BSP external thread — direct mounting on standard tank fittings, without special adapters\u003c\/li\u003e\n\n\u003cli\u003eCompact housing with emergency stop button — quick power cut-off in any situation\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-how\"\u003e\n\n\u003ch2\u003eHow it works and how to install it\u003c\/h2\u003e\n\n\u003cp\u003eThe pressure switch is mounted on the threaded port of the compressor tank (1\/4\" BSP) and electrically connected between the 230V AC source and the compressor motor. The internal mechanism detects the air pressure in the tank and automatically closes or opens the electrical circuit, depending on the pressure thresholds adjusted with the setting screws. Installation does not require special tools — a wrench and a screwdriver are sufficient for complete assembly in approximately 20 minutes.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-faq\"\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it compatible with any single-phase air compressor?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the pressure switch works with single-phase 230V AC compressors that use standard 1\/4\" BSP threaded connections and do not exceed 16A starting current per contact.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I adjust the start and stop pressure?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe minimum (start) and maximum (stop) pressure are adjusted separately via two accessible adjustment screws after removing the cover — no electrical reconfiguration is required.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat do the 4 outputs mean — can they power 4 tools simultaneously?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe 4 outputs are independent pneumatic or electrical connections (NO\/NC combinations) that allow control of multiple circuits, but the power capacity depends on the system configuration and does not necessarily mean 4 pneumatic tools in parallel.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-specs\"\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSKU\u003c\/td\u003e\n\n\u003ctd\u003eQ-3B025\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePressure adjustment range\u003c\/td\u003e\n\n\u003ctd\u003e2 – 12 bar (30 – 175 PSI)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eNumber of outputs\u003c\/td\u003e\n\n\u003ctd\u003e4 independent contacts (NO\/NC combinations)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConnection thread type\u003c\/td\u003e\n\n\u003ctd\u003e1\/4\" BSP (external thread)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMaximum current per contact\u003c\/td\u003e\n\n\u003ctd\u003e16A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eOperating voltage\u003c\/td\u003e\n\n\u003ctd\u003e230V AC, 50\/60 Hz\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\n\u003ctd\u003eAir compressor pressure switch\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eHousing construction\u003c\/td\u003e\n\n\u003ctd\u003eMetal body with plastic cover\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eEmergency stop button\u003c\/td\u003e\n\n\u003ctd\u003eYes (resettable red button)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-warranty\"\u003e\n\n\u003ch2\u003eWarranty and support\u003c\/h2\u003e\n\n\u003cp\u003eThe product benefits from a 2-year legal warranty in accordance with current Romanian legislation.
