The DK-Ex series features pulse reverse-jet cleaning and a safety explosion-proof design. Compared with standard industrial vacuum cleaners, it possesses a sturdy and durable structure with a wide power range. It is ideally engineered for continuous operation in explosion-proof zones, handling flammable and explosive dust, or acting as integrated support for industrial equipment.
Powered by an internationally advanced explosion-proof precision-cast turbine blower (air pump). It features wide voltage, dual frequency, high reliability, low noise levels, and extended operational lifespan—capable of continuous 24-hour operation.
Constructed with a flameproof enclosure fitted with high-tier Schneider brand components, including the internal AC contactor and thermal overload protector.
Comes standard with a negative pressure gauge customized by Puhua Company. The indicator reflects stage conditions:
Engineered for straightforward installation and effortless mobility. Wheels are fabricated from top-grade polyurethane (PU), mounted on 2.5mm pickled plate brackets with reinforcing ribs, and finished with textured anti-slip surfaces.
The upper-lower tank separation structure serves as the standard operational configuration of this machine, facilitating quick, ergonomic dust discharge:
Lift the pressure rod upward; the dust tank naturally drops down to the ground surface.
Drag the detached dust tank directly via its dedicated built-in casters to dump collected dust.
Return the tank to its operational position and press the pressure rod firmly downward to lock.
The DK-Ex series utilizes a certified flameproof explosion-proof electrical box rated with the explosion-proof marking Ex d II BT4, integrated with internal Schneider brand electrical components including the AC contactor and thermal overload protection.
Yes. Equipped with an internationally advanced precision-cast turbine blower (air pump) offering wide voltage and dual frequency capability, the unit delivers high operational reliability and low noise for uninterrupted 24-hour continuous performance.
The customized Puhua negative pressure gauge uses green, blue, and red sectors to map internal negative pressure across power stages. When the pointer shifts into the red zone, it alerts operators that the filter requires cleaning or replacement.
The machine features an upper-lower tank separation structure. Simply lift the pressure rod upward to lower the dust container to the floor, wheel it to the disposal area via its independent casters, empty it, and press down the pressure rod to reseal.
The DK-Ex is engineered for designated explosion-proof zones and flammable/explosive dust applications. Primary fields include metal processing, aluminum and magnesium processing, batteries, foundries, electronics, and additive manufacturing (3D printing).
The industrial casters utilize premium-grade polyurethane (PU) with an anti-slip textured pattern, supported by reinforced 2.5mm pickled steel plates with integrated ribs for maximum stability and easy mounting.
