Natural Ventilation Product Overview

TMS-D - Natural Extract Operable Roof Louvre

The latest version of our TMS ventilator.
Rated as an approved Smoke Extract / Fire Ventilator.
Available with press formed aluminium blades or glazed blades for light transmission.
Operation by pneumatic or electric actuators with fire set fusible link local release as required.
Typical Applications: A most economic unit, used extensively for Stairwell Systems, Warehouses, Industrial and Commercial Buildings including Shopping Centres.
Also suitable for daily ventilation.

TMS–DR - Roof Louvre with Weathered Side Ventilation

Rated as an approved Smoke Extract / Fire Ventilator.
Specification generally as for TMS D Roof ventilator but with the addition of two fully weathered side wings.
The side wing ventilators are available in 150mm or 300 mm sizes that can be continuously open or fitted with dampers to close off the air flow.
Typical Applications: Specified as a smoke extract ventilator as for the TMSD but specified where daily ventilation must also be available during rainfall conditions.
Also suitable for daily ventilation and special purpose applications.

TMS–DG - Natural Extract Operable Wall Louvre

This is the Vertical version of the TMS-D Roof Louvre.
Rated as an approved Smoke Extract / Fire ventilator.
Typical Applications: Used as a smoke extract ventilator in Jack Roof Constructions or in the side walls of glazed atria roofs.
Also suitable as low level air inlet, for smoke extract systems and for daily ventilation.

NKV-T - High Quality Extruded Aluminium Roof Louvre

Rated as an approved Smoke Extract / Fire ventilator.
This is similar to the TMS-D roof louvre but has flat interlocking extruded aluminium blades. This results in a stronger more Architectural product with high performance seals to minimise air leakage.
Typical applications: Used where Architectural appearance is important and where higher levels of sealing and insulation are required, to comply with new UK Building regulations.

NKV-TB - Curved Extruded Aluminium Roof Louvre

Rated as an approved Smoke Extract / Fire ventilator.
This is similar to the NKV-T extruded aluminium Roof louvre but is mounted on a curved base.
Typical Applications: This louvre is specifically designed to allow neat and unobtrusive installation into continuous dome-light constructions.

NKV-RT - Extruded Aluminium Roof louvre with Weathered side Ventilation

Rated as an approved Smoke Extract / Fire Ventilator.
Specification generally as for NKV-T Roof ventilator but with the addition of two fully weathered side wings.
The side wing ventilators are available in 150mm or 300 mm sizes that can be continuously open or fitted with dampers to close off the air flow.
Typical applications: Specified as a smoke extract ventilator as for the NKV-T but specified where daily ventilation must also be available during rainfall conditions.
Also suitable for daily ventilation and special purpose applications.

VR - Casement Window Ventilator

A modular operable top hung window unit available with solid aluminium single skin or insulated infill panels or a variety of glazed panels.
Mounted in a frame that can be thermally insulated or broken as required.
Operation may be by direct acting linear pneumatic or electric actuators or with chain actuators where actuator penetration into the space below is undesirable.
Typical Applications: Suitable for building into Patent Glazing Systems where flanges can be manufactured to match the glazed panel the ventilator is to replace.
Also suitable for wall mounting and for integration into Curtain Wall Systems.
Used extensively on glazed Atria and high quality Architectural buildings.
This ventilator is not suitable for Smoke/ Fire Ventilation.

NKVD-PF - Twin Flap Flat Profile Roof Ventilator

Rated as an approved Smoke Extract / Fire Ventilator.
A high capacity smoke extract ventilator with two flaps each operated by a linear pneumatic or electric actuator.
Available with a range of solid or glazed panel inserts to provide very high levels of insulation or sealing when required.
Bases are available in single skin aluminium, insulated construction or thermally broken and insulated construction.
Typical Applications: Generally specified for use on built up and cladded roof constructions where they are mounted on a suitable builders work up-stand.
The units provide a large free ventilation area to minimise the total number required.
Glazed units are not normally specified on flat roofs or where the roof slope is less than 5 degrees as inadequate drainage causes mould build up over time.
Also suitable for daily ventilation and special purpose applications.

NKVD-PS - Twin Flap Roof Ventilator with Sloping Flap Panels

Rated as an approved Smoke Extract / Fire Ventilator.
This unit is identical to the NKVD-PF unit except that the top flaps are sloping.
This improves water shedding and prevents water pooling when installed on Flat roof constructions.
Typical applications: As for the NKVD-PS but specified where high rainfall is expected or where the ventilator is on a flat roof with glazed insert panels, to improve drainage and minimise build up of deposits on the glass.
Also suitable for daily ventilation.

NKV-RD - Twin Flap Roof Ventilator with Weathered Side Ventilation

Rated as an approved Smoke Extract / Fire Ventilator.
This unit is identical to the NKVD-PS unit but has additional side wing ventilators that can provide continuous ventilation in rainfall conditions.
Typical applications: Used where smoke / fire ventilation plus continuous daily ventilation regardless of weather conditions is required. The side ventilators can be open or fitted with operable dampers.

Domelight, Ventlight and Smokelight, Operable Lightdomesr

This is a new range of low cost units designed to fulfil the needs of the building industry.
The Domelight is a fixed closed unit intended for daylight transmission only.
The Ventlight is similar but has an opening top panel that can be fitted with a pneumatic or electric actuator to open and close for daily ventilation purposes.
The Smokelight is an approved Smoke Extract / Fire Ventilator.
It is at present only available with pneumatic actuation.

MLS - Horizontal Wall Louvres

A range of press formed and extruded aluminium wall louvres. These fixed and operable louvres are used for air inlet for natural or mechanical ventilation systems.
Also suitable for special purpose applications.

NKV-G - Horizontal Wall Louvres

This is a new range of low cost units designed to fulfil the needs of the building industry.
The Domelight is a fixed closed unit intended for daylight transmission only.
The Ventlight is similar but has an opening top panel that can be fitted with a pneumatic or electric actuator to open and close for daily ventilation purposes.
The Smokelight is an approved Smoke Extract / Fire Ventilator.
It is at present only available with pneumatic actuation.
