This device instantly injects compressed air that has been stored under pressure into powders and granular materials blocked in large tanks or silos, breaking the blocked powder and granular materials with explosive force. Manually eliminating blockages in tanks and silos is dangerous and may cause personal injury. Direct Blaster replaces these dangerous tasks with the push of a button, allowing you to solve the problem safely and with peace of mind.
1．When compressed air is supplied through a three-way valve, the mushroom valve is pushed to the exhaust port.
2．The compressed air passing through the valve pushes the piston towards the discharge port.
3．The piston is pushed to its limit and blocks the discharge port, and the compressed air is charged into the tank through the tube.
4．Charging is complete when the supply pressure equals the pressure inside the tank.
5．When the three-way valve is switched, the compressed air inside the mushroom valve and piston is exhausted, drawn to the opposite side, and the compressed air in the tank is instantly ejected from the discharge port.
The video of working principle.
It blasts air directly on the material from the outside of storage, it is more effective and reducing dead stock in the silo.
Solving blockages inside tanks and silos had been done manually by operators, but it carries risks and easy to cause accident and personal injury. To prevent such risks, the blaster is widely adopted in many sites these days.
Using the mushroom valve system, injection power can be adjusted by changing supply air pressure.
The consumable parts inside the valve can be replaced on-site, improving maintainability.
The automatic control type allows manual operation, automatic single cycle operation and automatic contunuous operation by the select switch, enabling user to run the blaster according to the blockage condition.

2.2 kW compressor will be sufficient for using it.
※Please use a compressor with a discharge air volume of 200 L/min (ANR) or more (1.5 kW or higher).
In case of using a compressor with a discharge air volume of less than 200 L/min (ANR), connect a receiver tank of 10 L or more directly before the three-way solenoid valve.
