Turbo fan, high negative pressure vacuuming


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. Power is optional from 1.5kw-7.5kw, recommended power supply: 345~415V 50Hz or 380~480V 60Hz. You can also use single-phase power supply 220v/50Hz or 220v/60Hz, and the maximum power of single-phase power supply is 2.2kw.

Cartridge filter, quick release structure design


The filter system adopts filter cartridge filter, imported polyester fiber base material, adopts Puhua’s patented quick-release filter cartridge design, the installation and disassembly of the filter cartridge is very convenient, and provides great convenience for manual cleaning of the filter High performance, the disassembly and assembly of the filter cartridge can be completed within 1 minute.

Pulse blowback cleaning, automatic and efficient


The DGF series is equipped with pulse solenoid valves, pulse controllers, pulse nozzles, gas storage bags, oil-water separators, etc. required by the automatic pulse blowback system as standard. The blowback interval and frequency can be adjusted according to the amount of dust.
The principle of pulse blowback dust cleaning is that the jetted high-pressure air quickly enters the inner surface of the filter cartridge, causing the filter cartridge to expand rapidly, causing a shock vibration, and shaking the dust attached to the outer surface of the filter cartridge to the dust box below.

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.

Casters & fixed mounting base are optional to adapt to changing equipment installation methods


Industrial mobile casters are the default standard accessories of this machine. The wheels are made of top-grade polyurethane (PU), and the brackets are made of 2.5mm acid
Reinforcing ribs are added to the washing board, and a single 4-inch caster can carry 150kg. The wheel surface is designed with texture to enhance the anti-skid performance.
The fixed foot is an optional accessory, and the mobile industrial caster is optional. If the customer has a fixed installation requirement, our company can change the configuration to a fixed foot. The installation size can be customized according to the customer’s requirements. Please be sure to submit it before the order is confirmed.
