Description

A versatile and robust range of roof extract ventilating units designed to satisfy the requirements of efficient ventilation in commercial and industrial applications. The simple, proven design of Standard range makes installation and routine cleaning easy.

Featuring a low profile cowl, the unit is ready for fitting into horizontal, angled and vertical glass, fixing plates on roofs and in vertical windows or walls in exposed areas. With Vent-Axia roof plate assemblies, all four sizes can be fitted easily into flat roofs. Suitable for roof installation plus window and wall installation in exposed areas (eg: coastal positions).

Vent-Axia's spigot and ring method of fixing ensures easy installation and weather proof joint. We recommend the use of sealing compound under the upper part of the unit when fitted in roofs.

Motor

Purpose designed enclosed motor. Suitable for running at any angle. Quiet running, continuous rated motor with sealed for life ball bearings.

Suitable for operation in ambient temperatures from -40°C to +50°C.

Fitted with Standard Thermal Overload Protection. (S.T.O.P.)

Supply voltage 220-240V/1/50Hz.

Easy Cleaning

Integrated component design allows all parts to be dismantled for cleaning without the use of specialist tools.

Installation

All Standard Range roof models are designed to fit directly into horizontal and sloping windows including wired cast, up to 1mm thick.

In solid roofs, install using a roof plate assembly and, if required, and eggcrate grille in the ceiling below. A suitable sealing compound should be used between the glass/roofplate and the exterior seal.

Controllers

Rangemaster Controller
Infinitely variable speed control, adjustable minimum speed setting. Choice of extract/intake. Sensor mode switch enables any of a number of external electro-mechanical switches eg: Ecotronic, HumidiSwitch, ThermoSwitch and TimeSwitch to control the fan.

Multi-unit Controller
For groups of up to 5 units of any one size up to a total of 400 watts. Extract/intake and infinitely variable speed control. Do not mix T-Series with Standard Range ventilating units on one controller.

TimeSwitch
Electronic timer. Can be pre-set for a time overrun of 1-35 minutes. Maximum load 2 (1 inductive) amps.

Sensors

Ambient Response Humidity Sensor
Self programming electronic On/Off wall mounted humidity sensor which reacts to any rapid increase in humidity and temperature.Night time RH increment setback feature.

Air quality sensor
Automatically reacts to the depletion of air quality, sensing tobacco smoke, smells and toilet odours to regulate mechanically ventilated areas.

Ecotronic Humidity Sensor
The Ecotronic Humidity Sensor is an adjustable set point, solid state controller. A pullcord provides manual override, indicated by lamp. Adjustable from 65% to 90%RH. Ecotronic includes a relay and can be used with T-Series controller sensor mode.
