How to use the Product Selection Chart
1) Select your required application from the left hand column.
eg. Spa Bathroom (11-20 air changes per hour)
2) Calculate the volume of the room in cubic metres (m³) by multiplying the length x width x height.
eg. 3.2m x 3.2m x 2.4m = 24.58m³ (therefore select a room volume of 30m³)
3) Follow the row across and select one of the fans available which suits your mounting requirements, using the pictures and headings as a guide.
eg. Require a Roof Mounted Fan along the 11-20 air changes per hour with 30m³ air volume row (therefore select an ECEP204)
Notes on selection criteria
All selections are based on installed fan performance and maximum air change rate (ie. 10 or 20). Figures in brackets (eg. (8)), show actual air change rate if it is less than the maximum.
Selections for Wall Mounted fans are based on the fan’s optimal performance using 230mm length of wall tube.
Selections for Ezifit range fans (EIE, EWE and ECEP) and In-Line Duct Mounted fans are based on the fan’s optimal performance using 6m of duct. All flexible duct must be taut and straight. Longer duct runs may be possible. Please contact Fantech Trade for specific requirements. Selections for the Ezifit In-Wall (EIE) are based on the unit being wired in medium speed as standard.
