DG 300 SE PN

The DG 300 SE PN is a heavy-duty three-phase industrial vacuum designed to handle large volumes of dry dust in continuous industrial applications, making it suitable for dust-intensive environments such as manufacturing or processing facilities.

“PN” refers to the automatic reverse pulse filter cleaning system – the high-surface filter cartridges are automatically and systematically cleaned with reverse pulses of air so that dust build-up on the filters is prevented, maintaining suction performance.

Typical technical specifications include:

• Power: 23 kW (30.8 HP), three-phase (460 V – 60 Hz)
• Maximum airflow: 788.7 CFM
• Continuous water lift: 173.2 inH₂O
• Suction inlet: 5 in 
• Collection capacity: 58-gal
• Noise level: 77 dB(A)

Primary filter: antistatic polyester Class M cartridge (surface area 280 ft²)
These figures are taken directly from the official product technical data.

The DG 300 SE PN is built with a powder-coated steel frame, has a two-stage side channel blower for continuous duty (maintenance-free), a tangential inlet with cyclone protector, removable collection tank and forklift handling points for easy placement and mobility.

It uses high-surface antistatic polyester cartridge filters (Class M) that provide large filter area and are automatically cleaned by the reverse air pulse system. This helps maintain long-term performance with reduced manual cleaning needs.

Optional filter upgrades available from Delfin include: Certified HEPA Class H14 (very high efficiency), and PTFE-coated filters (for finer dust or specific environments). These options allow adaptation to specific industrial needs.
