Self-cleaning spray gun for polyurethane/polyurea spraying, compatible with mainstream equipment.
The P2 spray gun is a specialized spray tool designed for high-volume polyurethane foam (PUF) and polyurea spraying. It combines lightweight design, high trigger force, easy maintenance, safety and reliability to make spraying easier and more efficient, even at high ceilings, in tight spaces or at complex angles.

Lightweight and flexible, comfortable operation
Lightweight and ergonomic handle design, not easy to fatigue even after long time spraying.
Balanced design allows the operator to easily control the direction of the gun, even in difficult to operate position can be accurate spraying.
Dual Piston High Trigger Force Design
Twin-piston construction provides more than 300 lbs (136 kg) of trigger force, much higher than smaller diameter piston guns.
Sensitive triggering and continuous, uniform spraying ensures proper mixing of materials for improved application accuracy.
Easy-to-maintain construction reduces downtime
Mix chamber inserts are quickly replaceable, eliminating the need to replace the entire mix chamber.
Built-in check valve prevents liquid from seeping into the dry side, avoiding material backflow.
No need to use micro-drill to clean small air passages, making routine maintenance easier.
Anti-skip material design
Advanced anti-skip construction virtually eliminates the possibility of material escaping the air piston for safer, cleaner application.
Efficient Spray Performance
High and stable spraying flow reduces downtime and increases productivity.
Suitable for long periods of high intensity use, maintaining high output spraying capacity.
Safe and Reliable
Precise design ensures that material does not flow back, reducing the risk of leakage.
Anti-skip + check valve double protection for clean construction and safe operation.
