Low capacity and high pressure explosion-proof centrifugal fans with stainless steel casing and forward curved impeller designed for operation in explosive gas environments DIC ATEX INOX GAS ≤2400 m³/h

• DIC ATEX INOX GAS centrifugal explosion-proof fans with stainless steel casing, for use in explosive atmospheres (zone 1), up to 2400 m³/h
• DIC ATEX INOX GAS series centrifugal fans are designed and certified according to ATEX directive 2014/34/EU. These units with stainless steel construction are intended for continuous operation in industrial environments where a small amount of air at high pressure is required and corrosion resistance is essential

• other modifications of the DIC series fans:

1. DIC - centrifugal fans of the series are designed to transport clean and dust-free air and smoke with a temperature of up to +100 °C

2. DIC AT - centrifugal fans for the transport of clean air or fumes up to +150 °C

3. DIC INOX / AT - centrifugal fans with stainless steel housing for corrosive gases or fumes up to +150 °C only on special order, to be combined separately

4. DIC ATEX - explosion-proof centrifugal fans for the transport of clean air or fumes up to +40 °C

5. DIC INOX - centrifugal fans with stainless steel casing for the transport of corrosive gases or fumes up to +80 °C

APPLICATION AND CERTIFICATION

• DIC ATEX INOX GAS fans are specifically designed for use in zone 1 – environments where a high safety factor must be ensured against potential explosions due to gases, vapors, or mist (II2G)
• certification marking: II2G Ex h IIB T4 Gb
• additional versions upon request: options available for operation with dust zone 21 (II2D Ex h IIIB T135°C Db) and in hydrogen environment zone 1 (II2G Ex IIB+H2 T4 Gb)
• compliance with standards: EN 14986:2017, EN 1127-1, EN ISO 80079-36, EN ISO 80079-37

TECHNICAL DESCRIPTION

• fans feature a compact and robust construction, adapted for transporting corrosive clean air with temperatures ranging from -20°C to +40°C

CONSTRUCTION

• spiral casing made of AISI 304 stainless steel, which is suitable for transporting corrosive and acidic air. impeller: single suction, with forward curved blades (sirocco type), made of galvanized steel or stainless steel upon special request. casing is easily orientable every 45 degrees, standard position LG 270

MOTOR

• explosion-proof asynchronous three-phase or single-phase motor, IP55 protection class, F insulation class. motor is separated from the transported air flow

ADVANTAGES

• high safety level: motor is equipped with PTC thermistors protecting against overheating and is suitable for speed regulation by frequency inverter for three-phase versions
• maximum resistance: stainless steel casing ensures longevity in aggressive chemical environments
• compactness: ideal solution for industrial systems where high static pressure is required in limited space

ACCESSORIES

• the air intake and exhaust opening protective grilles are manufactured according to UNI 12499 rules and are protected from atmospheric factors

(see detailed dimensions and parameters on the manufacturer's catalog page)

Exhaust (OUT)	Intake (IN)

• steel engine support made of sheet steel, painted with epoxy resin (model 100 support is for a special engine, not required for standard model)
