Iso-Primo Sound-Insulated Inline Mixed-Flow Fans

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 ∅ 200 up to ∅ 250 mm air ducts.
Design

• The casing is made of galvanized steel, internally filled with 30 mm acoustic foam.
• Due to the conically shaped polymer impeller with specially profiled blades, the air stream circular velocity increases, which results in higher air flow and pressure, as compared to characteristics of standard axial fans
• Mixed-flow impeller made of high-quality plastic.
• The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high capacity, powerful
• pressure and low noise.
• External airtightterminal block on the fan casing for power supply.
• Mounting brackets on the fan casing for mounting to the ceiling.

Motor

• Three-speed single-phase high-efficient motor with low energy demand on ball bearings.
• All motors have manual reset thermal overload protection.
• 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 external thyristor or transformer speed controller (specially ordered accessory) when connected to the maximum speed terminal.

Mounting

The fan is suitable for mounting in any section of the ventilation system from intake to the end of the ductwork.
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.
G1: speed controller, temperature controller with external temperature sensor (cable length 4 m), power cable with mains plug.
GI1: speed controller, temperature controller with integrated temperature sensor 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.
W: power cable with mains plug.
