Silent Oil Free Ex Proof Vortex Fan

Cleanliness and quiet operation are typically the first casualties when equipment gets an explosion-proof rating - heavier enclosures amplify noise, and the added motor mass drives designers toward lubricated components. The Silent Oil Free Ex Proof Vortex Fan breaks this pattern by delivering all three attributes - silence, zero oil, and certified explosion safety - in a single dual-stage platform.

At the smallest end of the XGB-B series, the 0.37 kW XGB370-B operates at just 53 decibels, comparable to normal conversation in an office. Achieving this in an explosion-proof motor requires the integrated three-layer silencer system: a high-density sound-absorbing sponge cylinder inside the silencer pipe, a mesh silencer net providing secondary acoustic baffling, and a shock-proof steel base plate isolating residual vibration from the mounting surface. Together, these layers maintain a usable working environment even when the blower runs continuously indoors.

Oil-free operation comes from the regenerative side-channel principle used by all XGB-B models. The dual impellers compress and move air through the pump body without any contact between lubricated surfaces and the working gas stream. A dedicated oil seal isolates the bearing housing's grease cavity from the impeller shaft, creating a permanent physical barrier. The result is a clean airstream suitable for pharmaceutical clean rooms, food-grade grain handling, laboratory gas circulation, and any process where airborne oil contamination would cause product rejection or safety issues.

The silent oil free ex proof vortex fan is chosen for noise and cleanliness-sensitive hazardous applications: hospital chemical storage ventilation, pharmaceutical analytical laboratory fume extraction, food processing plant combustible dust control, research facility inert gas circulation, semiconductor clean-room solvent exhaust, and occupied industrial control room pressurization.

Standard performance envelope: 0.37–5.5 kW (50Hz), three-phase 200–480V dual voltage, 80–500 m³/h airflow, 120–320 mbar maximum discharge, -120 to -300 mbar maximum suction, 53–80 dB noise range. Twenty precision components, individual QC certification, aluminum alloy casting, copper motor winding. Shipped worldwide from Taizhou Yijia's Zhejiang factory - a design-develop-produce integrated manufacturer with daily output of over 8,000 blowers.

Worker health and safety in hazardous zones are the primary reasons for choosing our explosion-proof vortex air pump. At "work sites" involving tunnels or cramped construction areas, the pump is used for the "removal of toxic gas and local dust," ensuring that workers breathe clean air even in enclosed spaces. A major safety application is "welding gas suction," where the blower extracts the smoke and fine dust generated during welding through a vacuum system, protecting the operator's lungs and eyes from hazardous particulate matter.

The pump's "smoke blowing and suction" capability is also used in factories to quickly discharge emitted fumes before they can accumulate and pose a fire or health risk. For environmental protection, the blower is integrated into "gas decomposition" devices, attracting and moving harmful gases through buckets and filters for treatment. Even in specific machines like "ironing machines," the pump plays a safety role by sucking out hot steam, preventing the workspace from becoming dangerously humid or overheated. By using professional glands and rubber seals at the wiring ports, the pump itself remains a safe, non-ignition source in these gas-laden environments, providing a comprehensive safety solution for modern industry.
