• Internal motor fully sealed structure to resist oil mist and light dust erosion inside control room

Working Principle

After connecting 24 V DC cabinet power supply, the built-in brushless DC drive circuit drives the plastic impeller to rotate at fixed 3100 RPM. The fan extracts hot air accumulated inside the cabinet and discharges it outside the enclosure, while cold external air passes through G2 dust filter screen and enters the cabinet to form directional forced convection heat circulation. The speed detection circuit outputs real-time pulse speed signal to cabinet monitoring PLC; when fan impeller is locked by foreign matter, internal locked-rotor protection circuit cuts off motor drive current within 2 seconds to avoid burnout. Anti-vibration rubber pads isolate motor rotation vibration, preventing resonance interference to precision analog signal modules in the cabinet.

Advantage Highlights

1. Dedicated 24 V DC power supply matches unified industrial control cabinet power architecture, no additional AC conversion equipment required
2. Built-in speed feedback function realizes remote fan fault alarm without extra detection sensors
3. Detachable G2 filter screen reduces cabinet internal dust accumulation and extends service life of expensive SIS safety modules
4. Brushless DC motor zero carbon brush wear, ultra-long continuous service life suitable for unattended plant operation
5. Integrated anti-vibration structure avoids analog signal measurement deviation caused by mechanical vibration resonance
6. Standard 120 mm size universal installation frame compatible with all mainstream industrial control cabinet ventilation windows

Applicable Industries

SIL3 safety instrumented system cabinet heat dissipation, refinery ESD control room cabinets, power plant boiler safety PLC enclosures, chemical plant hazardous area auxiliary control cabinets, offshore platform local safety monitoring cabinets

Installation Requirements

1. Snap-fit install the entire fan assembly on 120 mm square reserved ventilation window of control cabinet outer panel
2. Install the fan in air-out direction to discharge hot air outwards; reverse air intake installation is forbidden
3. Connect power wiring to 24 V DC cabinet auxiliary power with matched 2 A slow-blow fuse protection
4. Tighten all four-corner fixing screws evenly to ensure the surrounding sealing rubber strip is fully compressed
5. Reserve minimum 100 mm unobstructed space outside the cabinet for fan air exhaust circulation
6. Install filter screen on the air intake side of the fan assembly, keep filter surface parallel to air flow direction

Usage Precautions

1. Cut off fan 24 V DC power before disassembling filter screen for cleaning to avoid accidental fan rotation injury
2. Clean the filter screen every 2 months in heavy dust workshop environment, replace filter mesh once every 12 months
3. Do not block fan air intake or exhaust channel with cables, pipeline or other cabinet accessories
4. Stop using the fan if rubber anti-vibration pads aging and cracking occur, replace complete assembly to avoid vibration interference
5. Spare fan units shall be stored in dry warehouse environment without long-term extrusion deformation of impeller
6. Operating ambient temperature exceeding +70 °C will sharply shorten brushless motor service life
