Description

A range of six In-Line Mixed Flow fans designed for use with rigid and flexible ducting with energy efficiency and low sound levels in mind. Vent-Axia Mixed flow fans offer almost two and a half times the pressure development of conventional axial fans making them ideal for many ducted applications. They are dimensionally compact and feature low noise and non-overloading characteristics.

The range consists of six sizes: 100, 125, 150, 200, 250 and 315mm with air volumes from 220 to 1860m³/h at free air, suitable against working pressures up to 400 Pa. ACM100T and ACM150T have built-in adjustable timers. All other models, with the exception of the ACM315 can be used with a timespan remote overrun timer, adjustable 3-25 minutes to comply with Building Regulations for internal rooms.

Suitable for most domestic and commercial applications particularly where space is limited. Their compact size makes them ideal for refurbishment work and in restricted ceiling voids. A full range of compatible ventilation accessories is available to create a variety of input and extract systems to suit individual schemes.

Compact mixed flow blade design with guide vanes provides optimum pressure characteristics. All sizes feature a removable motor body and impeller assembly for easy cleaning without removing ductwork.

Motor

All motors are fitted with Standard Thermal Overload Protection. (S.T.O.P.). Motors are speed controllable on their high speed setting. Designed for ambient temperatures up to +50°C.

Size 100 and 125 with shaded pole motors. Size 150, 200, 250 and 315 with capacitor start and run motors. All sizes are Class I appliances. Supply voltage 220-240V/1/50Hz.

Controllers

Electronic Controller - Surface mounting
Mixed flow fans are speed controllable (on high speed tapping only) using a Vent-Axia 1.5Amp electronic controller. It will provide infinitely variable speed control and features an On/Off/sensor slider with neon indicator. There is an adjustable minimum speed setting. The controller is radio suppressed to BS 800 and electrical connections for use with suitable external sensors are provided.

Typical Specification

Supply and install the ACM range of commercial In-line fans as manufactured by Vent-Axia Ltd, Fleming Way, Crawley, West Sussex, RH10 9YX, Telephone: 01293 526062.

The fan should be of the mixed flow design specifically for use with rigid and flexible ducting with energy efficiency and low sound levels in mind. The fan shall be fitted within the ducted system and isolated from the building structure by means of Anti- Vibration mountings.

The fans should be dimensionally compact saving weight and installation costs. The casing should be manufactured from galvanised sheet steel and manufacture is controlled to BS EN ISO 9001.

The fan should be fully speed controllable by using a variable speed controller.

The fan should be controlled by humidity, air quality or PIR sensor.

The fan motor should be removable by means of 2 Clip Bands for ease of maintenance.

Motors should have ball bearings greased for life to allow the fan to be installed at any angle and should have Class B insulation to allow the fan to work satisfactorily in ambient air temperatures from -30°C to +50°C and should be fitted with Standard Thermal Overload Protection (S.T.O.P.).
