High-voltage power, continuous escort

The power system adopts the international advanced precision casting turbo fan (air pump), wide pressure and dual frequency, high reliability, low noise, long life, and can work continuously for 24 hours. The power is optional from 0.25kw-15kw, the power supply can be single-phase 230V 50/60Hz, three-phase 220-240/345-415V 50Hz and 220-275/380-480V 60Hz, etc. Special voltage can be customized.

Cartridge filter, high filtration fineness

In terms of filtration system, the filter cartridge filter is selected, and the Japanese Toray polyester fiber base material is used. The standard configuration is made of polyester fiber oil-proof and waterproof material, and the filtration accuracy of dust with an equivalent diameter of more than 3 microns is over 99%, and a higher filtration accuracy filter cartridge material is optional.

Specially set the dust removal door, no secondary pollution

DG series basic industrial dust collectors require manual dust removal. In order to avoid dust splashing and secondary pollution caused by manual cleaning of the outer surface of the filter cartridge, we have installed a dust removal door on the back of the machine. Open the door and use an air gun to blow the filter. The inner surface of the cylinder can realize the cleaning of dust.

Electrical system, quality assurance

In terms of the electrical system, the main electronic control components adopt the international famous brand – French Schneider products. The turbine motor realizes the independent control of the electrical box, and has built-in thermal overload protection, phase loss, and reverse phase sequence protection. The control panel is simple and elegant, and can easily realize functions such as remote control and linkage control.

Negative pressure monitoring, dust cleaning reminder

Negative pressure gauge is a standard configuration component of the whole machine. It is specially customized by Puhua Company for industrial vacuum cleaners. Green, blue and red correspond to the internal negative pressure of the machine in each power segment. The pointer points to the red area to indicate that the filter needs to be cleaned or replaced.

Drawer type dust box, practical and convenient

The dust collection box adopts a drawer-type structure. When the dust is full, open the door panel, and the dust collection box can be pulled out to clean the dust, and then the dust collection box can be sent in after completion. Convenient, fast and practical.

Industrial casters, your choice

Industrial mobile casters are standard accessories for this machine. The wheels are made of top-grade polyurethane (PU), and the brackets are made of 2.5mm pickled boards to add reinforcements. A single 4-inch caster wheel can carry 150kg. The wheel surface is designed with texture to enhance the anti-skid performance.
