Forward curved blade centrifugal fans

Product available also in:Industrial and building ventilation fans - Standard airHigh Temperature

The centrifugal fans of the DIC-ATX and DIC INOX-ATX series are designed and constructed to operate in potentially explosive environments, according to the ATEX Directice 2014/34/EU.

They are suitable to convey clean and non-dusty air in the temperature range of -20°C +40°C. They are suitable for installation in zone 1/21, that are areas where it is necessary to guarantee high security against explosions and fi res due to the presence of flammable gas (II2G) or dusts (II2D). These fans are certifi ed by IMQ according to ATEX Directive 2014/34/CE and to EN 14986 (Certif cate IMQ 10 ATEX 018 X). They are suitable for all the industrial applications where small air volumes and high pressures are required. The series consists of different models with impeller diameter from 100 to 180 mm. The motor is directly fitted to the forward curved impeller. The casing is easily adjustable, also on site, to the required discharge angle every 45°, excluding 180° and 225°. DIC INOX-ATX is made in stainless steel AISI304 and is suitable for conveying corrosive / acid air.
