631271 Tribo II Complete Diffuser For Powder Coating Tribo Gun Powder Air Mixing Spare Parts

Fixed part No. 631271, a complete diffuser assembly specially designed for the Tribo II automatic tribo electrostatic powder spray gun, standard non-purge version. It follows the original explosion drawing structure and dimension tolerances, so all sub-components match precisely for seamless assembly without modification. The full set includes the diffuser nozzle, housing, silicone O-rings, PVC connector, male connector and hose clamp, delivered as a pre-assembled complete kit. Quick disassembly supports inspection and part swap, greatly cutting downtime for production line maintenance. Stable batch production makes it ideal for global powder coating distributors, finishing workshops and spare part suppliers.

This diffuser works as the core upstream mixing unit for tribo charging. Compressed carrier air carries powder into the chamber to form a homogeneous powder-air mixture and accelerate particle flow before it enters the friction charging module. The calibrated internal flow channel avoids uneven powder concentration and pulsating flow, delivering a consistent frictional charging effect. Suitable for continuous automatic reciprocating spraying, it helps improve powder transfer efficiency and reduces coating powder waste. Compatible with epoxy, polyester, hybrid and metallic powder coating materials commonly used in the industry.

The main diffuser housing and nozzle adopt high-performance engineering plastic compatible with PTFE, featuring excellent impact resistance and a long service life under continuous high-speed powder scouring. Sealing O-rings are made of high-quality silicone, resistant to powder adhesion, aging and compression deformation under normal working pressure. The smooth inner cavity surface reduces powder accumulation, caking and clogging during long-hour production runs. Reliable sealing performance prevents air leakage that would otherwise break the stable tribo charging condition.

Matched with standard factory air parameter settings: flow rate air at 1.8 bar / 26 psi, diffuser air at 2.5 bar / 36 psi. Stable pressure holding ensures predictable spraying output and uniform coating thickness on workpieces. The threaded connection fits perfectly onto the gun extension, with a standard tubing interface for the diffuser air hose and powder feed hose. The simple structure allows operators to take it apart for full blowing and cleaning, supporting fast color change in multi-color coating lines.

A high-frequency wearing consumable for Tribo II friction powder coating guns, with an economical replacement cost to help control overall production expenditure. Built for automatic spray systems, it is compatible with reciprocators and fixed gun stations in mass finishing plants. No special professional tools are required for routine replacement and cleaning; on-site operators can complete the operation quickly. Sufficient spot stock is maintained for wholesale orders, with fast shipment supported for urgent maintenance demand.
