High Performance Components

At ADM we carefully select all components which make up your ventilation system. They must be fit for purpose, easy to use and robust. Equally, they must positively contribute to energy efficiency and provide you with value for money. View our high performance components brochure.

High Quality Ducting

We supply as standard, QuickTube, a rigid smooth bore circular ducting system for optimum performance. It is the most efficient, designed to minimise air turbulence, reduce pressure loss and noise.

All components are: High Quality Ducting
• Independently tested for performance and safety
• Complies with relevant Building Regulations
• Manufactured to strict quality control procedures
• Made using recycled plastic wherever possible
• Designed with ease of installation in mind
• Non-corrosive
• Available in three sizes:100mm, 125mm and 150mm

Having a smooth inner surface reduces the friction and turbulence caused by moving air. Crucially this minimises noise and results in more economical
operation. Because QuickTube is rigid it will not crush easily nor is it as prone to damage compared with flexible or semi rigid ducting.

Insulated Ducting

To protect against heat loss and condensation, we recommend that the ducting be insulated where appropriate.
We supply a range of ducting which is wrapped in an insulation of bubble wrap with aluminium foil. It contains no CFCs and meets Class 1 requirements tested to BS476 Part 7. It meets both IP 13/94 for Passive Stack Ventilation and BRE 398 for Heat Recovery Ventilation. Complies with SAP Appendix Q Guide.

Airflex

This innovative system uses low resistance, smooth bore tubing to individually connect each room to the heat recovery unit via an Air Distribution Box. By directly connecting each inlet/outlet there is zero leakage, so no loss of valuable regained warm air. Also the bore of the duct is coated with anti-static coating ensuring hygienic conditions and easy to clean simply by purging with a high pressure vacuum cleaner.

Room Terminals

It is important that the air movement induced throughout your home is imperceptible. ADM’s expertise in design means that your system will operate not only in accordance with Building Regulations (where appropriate) but also without any annoying draughts or noise. Neat low-profile circular vavles are normally used to supply and extract air in the rooms. They have been specially developed to minimise noise.

At the same time ADM's supply valves diffuse the incoming fresh air laterally in order to avoid uncomfortable draughts.

Adjustment of the airflow is straight-forward, the inner cone is simply rotated to the required setting and locked in position with a single nut. Each air valve comes with a pair of mounting rings from which it can be easily removed for cleaning without affecting either its setting or the integrity of the ceiling or wall. For safety in the kitchen, the extract valve incorporates a fire damper which is designed to close when the temperature reaches 70˚ C.
You should always seek advice from Building Control regarding any matters on fire regulations.

External Wall Terminals

Wherever possible we recommend the use of louvre grilles with a minimum of 2 metres separating the extract and supply. Neat, low -profile and easy to use they can be simply mounted into the gable wall or soffit.

Cowled outlets can also be used to protect against the effects of high winds and driving rain.

• Available in different sizes, with round spigots or rectangular
• sockets to fit all ducting systems
• Various types for different applications
• External and internal options
• Choices for the wall, soffit and roof
• Manufactured with UV stable materials to reduce colour fade
• Airbricks meet British Standard BS493
• Excellent air flow performance
• Easy to install
• Non-corrosive
