Hydor HIT Metal Inline Fans – a QUALITY brand for residential, commercial  and industrial exhaust or supply air application. Direct connections to standard diameter circular ducting and comes standard with manufacturing.

Please make sure that these fans are wired up CORRECTLY ! Although the fan may function for a period of time when wired INCORRECTLY, it will soon burn out the motor’s windings, rendering it obsolete. This is not covered under warranty and will not be refunded or swapped out.

AND ANOTHER THING… When adding an inline duct fan to a fan speed controller, rheostat or dimmer switch, the fan must ALWAYS be set to its HIGHEST speed setting!

Compared with sleeve bearing, ball bearing has the following advantages:  Long life, low maintenance, low temperature compatibility.

How to work out the size and type of fan required:
In order to provide adequate ventilation for a given application, it is essential the
correct size, type and number of units are selected. Selection of the correct fan depends on two
principal factors: the performance and application.
Step 1
Determine which mounting arrangements meet your requirements
Step 2
Calculate the VOLUME of the room in cubic meters (m3) by multiplying the length x width x height.
Step 3
How many air changes (AC/H) are required. Work out how fast one complete ‘air change’ needs to be carried out under warm conditions (i.e. the maximum you will ever need the fan to operate).If excess heat in a certain growing environment is a common problem, or there is a large volume of plants growing in a very restricted space you will need more air flow per hour than for a larger growing area which doesn’t suffer from too much heat build up with smaller plants. Growers commonly underestimate just how much ‘air exchange’ is required to remove excess heat and humidity, bring in fresh CO2 and generally create fresh air movement over all of the plant surfaces. As a comparison to greenhouse crops growing in full sunlight – one air change per minute or 60 air changes an hour are often aimed for with large, mature crops growing under warm, humid conditions. However, in a grow room situation, one complete air change obtained in 4-5 minutes is acceptable. Obviously this needs to be more frequent (one complete air change in 2-3 minutes) where lighting is creating a lot of extra heat to be removed or when a CO2 generator is being used.
Step 4
Use the following formula: Volume (m3) x AC/H = Airflow (m3/h)

Step 5
Select a fan that does the airflow you require.
