Delfin DG 70 EXP Z2/22
The Delfin DG 70 EXP Z2/22 is the top model in the DG EXP range with a 5.5 kW side-channel blower, 530 m³/h airflow and 3600 mmH₂O suction (3000 mmH₂O continuous) -- significantly higher output than DG 50 EXP in the same chassis. It is certified II 3GD including the control box, allowing use in Zone 2 gas and Zone 22 dust simultaneously. The enlarged 52.000 cm² HEPA post-filter provides lower air load and longer intervals between filter replacements -- ideal for production environments with high duty cycles.

Questions and answers
Why choose DG 70 EXP over DG 50 EXP?
Higher airflow (530 vs 420 m³/h), higher max vacuum (3600 vs 3200 mmH₂O) and double the HEPA post-filter area (52.000 vs 26.000 cm²). Choose DG 70 EXP for high duty cycles and longer service intervals.
What continuous duty is supported?
3000 mmH₂O is the stated continuous vacuum -- the blower is designed for 24/7 duty without time limit.
Is it heavier than the DG 50 EXP?
Yes -- 150 kg vs 137 kg. Both are mobile on wheels.
Why 20.000 cm² primary filter -- isn't that smaller than the DG 50?
Yes, but the larger HEPA post-filter (52.000 cm²) compensates fully. Net filter life is longer, not shorter.
Can it be coupled to a stationary explosion-protection solution?
Yes, via supplementary flame-retardant hose and bonding kit -- contact Particulair for configuration.
Is it EN 17348-compatible?
The factsheet marks "Dry type dust collector -- EN 17348 DT". It therefore meets the harmonised standard for dry-type dust collectors in explosive zones.
