Features and Technology
The Delfin DG30 EXP EX1/2D is a stationary dust collector designed for permanent installation in ATEX Zone 21 and Zone 22 areas. The equipment is third-party certified to EN 17348:2022 and EU Directive 2014/34/EU as category 1/2D, meaning it is approved for both gas (Zone 1) and dust (Zone 21/22) explosive atmospheres. Triple capacity (100 L) and higher airflow make the DG30 EXP EX1/2D ideal for larger industrial, pharmaceutical, and chemical processes.
The side channel blower is a premium motor type designed for continuous 24/7 operation without maintenance. There are no carbon brushes, ball bearings, or mechanical wear parts. It delivers 420 m³/h airflow with 2,400 mmH₂O maximum vacuum — a perfect balance of power and stability. The H14 HEPA filter guarantees 99.995% particle retention even at very high particle concentrations, perfect for pharmaceutical and cleanroom production.
AISI304 stainless steel as standard ensures maximum corrosion resistance in aggressive factory environments with chemicals and organic dust. Manual filter cleaning means short downtime. IP65 classification provides protection against moisture and particulates. The 100 L collection tank offers high flexibility for high dust production volumes.

Frequently Asked Questions
ATEX Zone 21 means explosive dust-air mixtures may occur 10 to 1,000 hours per year under normal operating conditions. Zone 21 is a higher risk classification than Zone 22 and requires more robust construction. The DG30 EXP EX1/2D is certified for Zone 21 and can also be used in Zone 22. Zone selection depends on installation and operating conditions.
II 1/2D means the equipment is certified for both Zone 1 (explosive gases) and Zone 21 (explosive dust) at ATEX category 1/2 — the highest safety level. This ensures the DG30 EXP EX1/2D can operate in very aggressive environments with both gas and dust explosive atmospheres.
The side channel blower has no carbon brushes, ball bearings, or mechanical wear parts. It is designed for continuous 24/7 operation without maintenance. Compared to centrifugal blowers, it delivers higher vacuum and stability at high particle concentrations, making it ideal for aggressive dust types in pharmaceutical and chemical environments.
Yes, the H14 HEPA filter (99.995% at MPPS) is included as standard. The filter has 26,000 cm² of filtration surface area and guarantees extreme particle retention for pharmaceutical, cleanroom, and chemical production. The primary filter provides 30,000 cm² of additional filtration capacity.
Options include: standard AISI304 stainless steel collection tank (X), tank and filter chamber in stainless steel (XX), and full AISI304 stainless steel construction with frame and cover (XXX). All variants ensure maximum corrosion resistance in aggressive industrial and chemical environments.
Yes. The DG30 EXP EX1/2D is third-party certified by IMQ, an accredited notified body for ATEX equipment.
