Product Overview

Product Overview

The Modular Ventilator will provide Trickle Ventilation in accordance with the Building Regulations 2000: Part F: Approved Document F1: October 2010 Scottish Building Regulations October 2011: Standard 3.14

This product is better suited for use with frame extension or header profiles and as such should be considered an ‘over the top vent’.

The products key features are as follows:

  • Modular design allows various equivalent area vents to be built from the standard base module. This reduces stockholdings. The Modular design is available assembled if required.
  • BBA Certification
  • Small footprint of only 138 mm x 26 mm for the base 2000 module. Spring clip fitting. (No screws)
  • Unique closure mechanism provides for adjustable ventilation with a positive action.
  • Optional modular grille or conventional canopy for exterior use.

Product Detail

Product Detail

The product consists of an internal unit with adjustable closures to regulate incoming air flow and a choice of external protective screens.

Internal ventilator

The product is based on a modular concept. The base module carries a male and female dovetail on opposite ends. This allows them to be quickly joined to give the required equivalent area. Complimentary end caps are then fitted to complete the assembly. Product is of course available assembled to customers requirements.

The modules carry a moulded pair of spring clips that enable them to be firmly snapped into the routed slot in the profile. This has obvious cost savings when compared with “Screw Fitting” alternatives.

The unique patiented closure action, gives two intermediate opening positions as well as “Closed”and “Fully Open”.

External canopy

The modular and snap fitting features, as well as footprint, are common between internal and external units.

An alternative exterior units are available.
FLAT GRILLE Designed primarily for installation in a near horizontal plane.

Installation Instructions

Installation Instructions

Installation simply requires the routing of a 19 mm (3/4 inch) slot through the profile. In order to preserve the maximum structural integrity of the profile the use of separate slots for each 2000 Module is recommended. i.e. Leave 6.5 mm bridgings between modules.

Ensure that the ventilator is correctly positioned relative to the routed slots prior to snapping the ventilator into place; as the installation is permanent.

  1. Typical of all sizes
  2. Use a 19 mm or 3/4 inch diameter cutter
  3. Rout a Slot 132 mm x 19 mm for each Module
  4. Leave 6.5 mm Lands between modules for multi-module installations
