Do inline duct booster fans work?

The short answer is yes. Duct fans definitely do work. Knowing a little more about how and why can help determine if they are the right solution to a particular problem. In general, duct booster fans are designed to regulate the flow of air out of vents across an HVAC system.

Where should inline duct fans be installed?

For maximum performance and minimum noise, the best location to install your In-Line Duct Fan™ is 6 – 10 feet from the register you wish to boost air to. To prevent air leaks use a good quality duct tape to seal seams in the ductwork after installing the In-Line Duct Fan™.

Can you put 2 inline fans together?

Many custom-designed setups require more ventilation than a single fan can deliver, so this can prompt the question whether two (or pairs of two) fans should be placed in series or parallel operation. In general, combining axial fans in series does not increase the airflow but increases the air pressure.

Are inline fans better at pushing or pulling?

Inline extraction fans are commonly designed to be positioned close to exit vents so that they extract (or suck) air from a room. However, when used as part of an air-cooled lighting system, it’s preferable to push air over your lamps that is, your inline fan is positioned before your air-cooled reflectors.

How do you increase air flow in ductwork?

Increasing airflow in ductwork can be done by cleaning the air filters and ductwork. By adding inline duct booster fans and/or air dampers significantly can improve airflow in weak areas.

How much electricity does an inline fan use?

Comparing 12-inch models, typical inline fans use about 250 Watts of electricity. Similarly sized booster inline fans in comparison use only about 100 Watts of electricity, but have significantly lower airflow capability overall.

How far can you duct an inline fan?

Any duct run of that length usually has bends in it too. Inline fans can comfortably sit on duct runs of up to 10m – and remember, the extraction rate is far higher to start with.

How do you size a duct booster fan?

Method 1: Multiply the room area by 1 to get approximate CFM (cubic feet per minute) required. Method 2: Multiply the furnace airflow (you can guess at 400 CFM per ton of AC) x % of house floor area served by the duct.

Does adding more fans increase CFM?

This article will answer a common question we receive: does stacking fans double the CFM (cubic feet/minute)? In short, stacking 2 (or more) fans will not double the airflow.

Will stacking fans increase airflow?

Stacking fans will not increase performance. It will not increase the speed of air pushed through, in fact it may lower it, just because the front fan may disrupt the airflow.

Is it better to push or pull air through a carbon filter?

Can-Lite filters come with pre-filters to keep dust, mold, and other particles from clogging the activated charcoal in the filter itself, so you should be pulling air through the filter rather than pushing air into it. You may have both supply and exhaust fans, depending on the size of your grow operation.
