Pool & Spa Ventilation


04 2114 1105

Pool and Spa ventilation – if not done correctly will lead to considerable cost in future maintenance.

Moisture precipitation (indoor rain)
Mould (consequence of bacteria + fungus growth)
Unpleasant Odour (indicating presence of mould)
Degradation of materials (consequence of heat, moisture, + salt)
Unhealthy environment (causing respiratory problems)

Indoor Pool and Spa ventilation is a top priority and essential element in the initial planning of this area.
Careful consideration is to be exercised as heated wet areas, particularly in winter months, where the moisture has the potential of precipitating on the surfaces and absorbed into the building fabric enclosing the area.

Air Ingress

Ventilation of a wet area is dictated by heat and pressure so balanced air ingress and egress is essential to ensure efficient air wash of area.

In all cases the ingress to egress dynamic is to be appropriate to the characteristics and dimensions of the ventilated area.

To be noted:
Install air ingress points opposite to egress.
The location of roof ventilators are ideally over pool area.
Ventilation performance is essential to service the area.
At Condor, aesthetic considerations in planning are secondary to essential services.


Recirculating air through a dehumidifier will remove the moisture but not the odour.
This expensive type of quick fix will seemingly get you out of trouble short term but will not improve the air quality.
Air volume exchange, in both appropriate quantity and quality, is critical.

Ignorance regarding appropriate ventilation will result in high maintenance costs and disappointment.
With salts present this wet area cannot be considered as an oversized wet area simply requiring a bathroom exhaust fan.
Natural air ingress is preferably within 600mm from the ground and ideally on southern side of building.

Efficient natural movement of air through the building is facilitated using the in Low / out High dynamic.

Powered egress on roof establishes an inefficient flow path from ingress to egress.
This manner of air washing the area is not recommended.
Good low level air ingress, passive or positive, is required, either .

A roof mounted fan for removal is not recommended but good air ingress during summer months is.
The venting of an Indoor Pool and Spa area is something you cannot afford to get wrong and very costly if ignored from the outset.

Indoor Pool / Span Ventilation (positive mechanical ingress)

Positive ingress where low level peripheral natural air ingress is not available. This method is for air ingress only.
Do not use mechanical for air egress in a pool area.
