Axial Flow Roof Units - RDE / RVE Series

  Features

  • The range covers sizes 200 - 1000mm diameter with Elta axial flow impellers.

  Construction

  • The AMS range of roof units are precision manufactured from glass fibre re-enforced polyester resin giving a strong yet lightweight construction.
  • The cowls have been aerodynamically designed to produce the minimum possible resistance to airflow whilst offering full protection against the weather.

  Motors

  • Totally enclosed IP55 tested to BS4999 and BS5000 and suitable for exposure to weather.
  • Standard voltages are 400 volt and 230 volts nominally.
  • Single-phase IP55 speed controllable motors are available.
  • The rotorex motors are IP44 protected with a working temperature of -40°C to 40°C.

  Special features

  • Refer to p D-2. High temperatures smoke spill fans are available.
  • Special voltages, speeds and classes are available on request.
  • Special finishes in hard gloss gel coats are available.

Soaker Sheets

  • Soaker sheets are available in most modern roof profiles complete with integral upstands.

Selection procedure

  • The units are selected of the standard AMS axial flow curves allowing a K factor of 1.0 for the RDE and a K factor of 1.25 on the RVE.

TDE

The Multiflow TDE 500 to 710 range consist of fully cased, cylindrical models with circular mounting flanges at both ends and a wired terminal box.

RVF

The Mini Centrifugal Roof Fan series are the new type roof extract units available in 2 sizes and suitable for vertical and horizontal installation. The low noise external motor and high efficient backward bladed impeller meets the requirement of efficient ventilation in residential, commercial and light industrial applications.

Future 150

The Decor Series can be wall or ceiling mounted and is designed to exhaust stale and moist air from bathrooms, toilets, laundries etc. They are also suitable for ventilating all types of small or closed areas.

TD Silent

The Silent Series is a low profile mixed-flow in-line fan that produces low noise when in operation. It does this through a specifically designed perforated internal skin that directs sound waves produced inside the fan to a layer of sound absorbent material.

NEW!! TD-EVO

The low-profile TD-EVO 250 and 315 in-line mixed-flow fans for circular ducts have a unique design where the support bracket allows the motor and impeller assembly to be fitted or removed without dismantling the adjacent ducting.
