~ Anti-static filter, eliminate the hidden danger of static spark ~
   

For the filtration system, a cartridge filter is used, and a Japanese Toray polyester fiber substrate is used. Standard configuration of PTFE membrane material, the filtration accuracy of dust with an equivalent diameter of 0.3 microns or more can reach more than 99%, and a filter cartridge material with higher filtration accuracy can be selected.

The surface is coated with aluminum film, with good antistatic performance, and the surface resistance is ≤106Ω.

~ Pulse back blowing dust removal, good effect ~
   

The pneumatic pulse blowback system consists of a cylinder, an electromagnetic pulse valve, a pulse controller, and compressed air. One end of the pulse valve is connected to a compressed air storage cylinder and the other end is connected to an injection pipe. An exhaust valve is installed on the valve cover, and the exhaust valve is controlled by a pulse controller.

When there is no signal from the pulse controller, the pulse solenoid valve starts to work, and each time the ash cleaning is completed at about 0.1 to 0.3S, it is the high-pressure air that is sprayed at this instant to play a good ash cleaning effect. Air enters the filter cartridge at a high flow rate, causing the filter cartridge to expand rapidly, causing an impact vibration, causing the dust attached to the filter cartridge to be shaken off, and the fine dust adsorbed on the surface of the filter material is shaken into the dust collecting bucket under the action of the airflow .

~ Explosion-proof configuration of pulse backflush system ~
   

Using the best filter cartridge cleaning technology so far, automatic pulse back-blow cleaning, and combined with the specially developed spiral injection technology, the cleaning area covers the entire surface of the filter cartridge, and there is no blind area for cleaning.

Explosion-proof machine uses explosion-proof solenoid valve, explosion-proof mark: Ex d Ⅱ CT5.

~ Standard vents ~
   

DFL-EX explosion-proof industrial dust collector uses a vent diaphragm device, which can blast at a specified temperature and pressure, and release the pressure.

To protect the safety of pressure-bearing equipment and the life of the operator, and to avoid greater damage to the environment in which it is used, the burst pressure of the bursting diaphragm is 0.01Mpa, and there is a professional certificate identification card.

The vent diaphragm is located at the rear of the machine. This diaphragm has good rigidity and fatigue resistance, and will not be prematurely damaged due to continuous operation of the machine; once a dust explosion occurs, the explosion-proof diaphragm will quickly rupture and release pressure, preventing the machine from secondary explosion.

~ Drawer type dust box, practical and convenient ~
   

The dust collecting box adopts a drawer structure. After the dust is full, open the door panel, and the dust collecting box can be pulled out to clean up the dust. After the dust collecting box is completed, the dust collecting box can be sent in. Convenient, fast and practical.

~ Industrial non-slip casters, top polyurethane material ~
   

Industrial mobile casters are standard accessories for this machine. The wheels are made of top-grade polyurethane (PU), and the bracket is made of 2.5mm pickling plate to increase the reinforcement. Each 4 inch caster can carry 150kg. The tread design of the wheel surface enhances the anti-skid performance.
