No complex tools required; simply screw the M30 fire extinguisher-specific connector into the extinguisher’s nozzle to create an airtight seal. Within minutes, a portable air supply system is ready for use.

2. Integrated multi-functional design
This assembly incorporates all key components required for air circuit control, eliminating the need for additional accessories:
High-precision pressure gauge: Monitors the pressure inside the cylinder (kg/cm²) in real time, providing clear visibility.
4mm two-way ball valve: Reinforced design with a smooth feel, allowing for effortless control of the air flow.
C-type self-locking quick-connect female fitting: A universal interface that is plug-and-play, allowing for rapid connection to pneumatic tools such as air blow guns, air nail guns and paint spray guns.
Standard inflation valve: Convenient for connecting to an air compressor or high-pressure air pump to refill the air tank.

3. Dual Safety Protection
Standard model: Recommended operating pressure not exceeding 8 kg, with a pressure-resistant design rated at ≤12 kg.
Upgraded Model: Equipped with an 8 kg safety valve that automatically relieves pressure when the internal pressure exceeds the rated value, eliminating safety hazards and ensuring greater peace of mind during use.
