Description
USE

Supply and extract ventilation systems installed in various premises with high requirements to the noise level. For ventilation air ducts requiring high pressure, powerful air flow and low noise level. Compatible with Ø 100 up to Ø 315 mm air ducts.

DESIGN

The casing is made of polymer-coated steel, internally filled with 50 mm mineral wool thermal- and sound-insulating layer. Special inner perforation of the casing and sound-insulating material are designed for wide-frequency sound absorbing. Mixed-flow impeller made of high-quality plastic. The diffusor, the specially profiled impeller and directing vanes provide high performance and powerful pressure combined with low noise operation. External airtight terminal block on the fan casing for power supply. Mounting brackets on the fan casing for mounting to the floor, to the wall or ceiling.

MOTOR

Double-speed (three-speed for Iso-Mix 200) single-phase high-efficient motor with low energy demand on ball bearings. Overheating protection due to built-in thermal switches. Motor ingress protection rating IPX4.

SPEED CONTROL

Speed selection with a built-in speed switch (US option) or an external multi-speed controller (specially ordered accessory). Smooth speed control is possible either with an integrated speed controller (FR1 option), an external thyristor or transformer speed controller (specially ordered accessory) when connected to the maximum speed terminal.

MOUNTING

Due to its compact design the fan is the ideal solution for mounting in limited spaces. The fan is suitable for mounting in any section of the ventilation system from intake to the end of the ductwork. Wall or ceiling mounting with a special mounting plate on the fan casing.

  MODIFICATIONS AND OPTIONS

T: turn-off delay timer adjustable from 2 to 30 minutes. US: three-position speed switch. FR1: smooth speed controller adjustable from 0 to 100 % and power cable with mains plug.

G1: speed controller, temperature controller with external temperature sensor (cable length 4 m), power cable with mains plug.

GT1: speed controller, temperature controller with external temperature sensor (cable length 4 m), 5 min timer switch and power cable with mains plug. GI1: speed controller, temperature controller with integrated temperature sensor and power cable with mains plug. GTI1: speed controller, temperature controller with integrated temperature sensor, 5 min timer switch and power cable with mains plug. The G1 and GI1 modifications enable automatic speed control depending on indoor temperature. The optimal ventilation solution for premises requiring permanent temperature control as greenhouses, orangeries, etc. W1: power cable with mains plug.
