VENTILATION & DUCTWORK

Better airflow. Better spaces.

Fresh-air, extract and ductwork solutions for spaces that need air to move properly.

01 / UNDERSTAND THE SYSTEM

Ventilation & ductwork in context.

Ventilation replaces or removes air; air conditioning primarily controls temperature. A comfortable building needs both to be considered together.

A room can feel cool and still need better ventilation. Air supply, extract and replacement air should be considered together.

Fresh-air systems

Bring outdoor air into occupied spaces through a planned arrangement suitable for the building.

Extract systems

Remove air from areas with odours, moisture or process requirements, with replacement air considered.

Duct distribution

Ducts, fittings, grilles and dampers influence airflow, noise and access for cleaning.

02 / SCOPE & CONDITION

What we look at.

Area	What matters	Why it matters
Poor airflow	Fan duty, duct resistance and obstructions	A fan cannot be selected from duct diameter alone.
Noise or vibration	Fan condition, mounting and air velocity	The source should be identified before replacing equipment.
Condensation	Air temperature, humidity and insulation	Outdoor-air treatment and vapour control may be relevant.

Work that can be included

Fresh-air and exhaust fans
Duct installation and modifications
Grilles, diffusers and access provisions
Fan repair and replacement

Define the scope before work starts.

Parts, quantities, access, shutdowns and reinstatement are confirmed against your site and equipment. Additional defects or specialist works are discussed separately.

03 / HOW THE WORK PROGRESSES

A clear route from enquiry to completion.

01
Define the space
Identify occupancy, use and the required air movement.
02
Assess the route
Review intake, discharge, duct routing and access.
03
Install or rectify
Carry out agreed fan, duct and accessory works.
04
Review performance
Check operation and airflow where included in the scope.

04 / COMMON QUESTIONS

A little more clarity.

Does an air conditioner bring in fresh air?

Many room split units mainly recirculate indoor air. Fresh-air provision requires a suitable ventilation arrangement; it should not be assumed from cooling alone.

Does a ceiling cassette provide fresh air?

Not automatically. Some models allow a limited fresh-air connection, but the actual installation and ventilation provision must be checked.

Can a bigger exhaust fan solve poor ventilation?

Only if the complete system supports it. Replacement air, duct resistance and discharge arrangements all matter.
