Summary
High-flow dust collector for fine, lightweight airborne dust, intended for ATEX Zone 22, model Zefiro Cube 20 K4 PN Z22.

Description
The Zefiro Cube 20 K4 PN Z22 is an industrial high-flow dust collector designed for continuous extraction of fine and volatile dusts in ATEX Zone 22 environments. It is suitable for industries requiring intensive dust removal such as pharmaceutical, food processing, metallurgy and welding operations. Equipped with a three-phase motor-fan unit rated 4 kW, it delivers a maximum air flow of 3,500 m3/h and a vacuum up to 370 mmH₂O. The motor is IP65 rated for continuous operation in dusty atmospheres.

Filtration system
The primary filtration uses two antistatic polyester cartridge filters treated with Teflon to reduce particle adhesion. Total filter area: 200,000 cm². Automatic pulse reverse pneumatic cleaning provides regular filter de-dusting without stopping the unit. A secondary HEPA H14 stage is integrated, capable of retaining 99.995% of ultrafine particles down to 0.18 micron to ensure purified and safe exhaust air.

Construction and ergonomics
Epoxy-painted steel construction providing mechanical resistance and long service life. 90 L removable tank for easy emptying. Forklift pockets ensure mobility. An optional articulated extraction arm is available for local source capture.

Comfort and safety
Sound level: 74 dB(A). The Zefiro Cube K4 is designed to operate continuously in demanding industrial environments while meeting ATEX compliance for Zone 22.
