Dryer Vent Booster Fan: Everything You Need to Know

The dryer vent booster fan :

helps out boost airflow between the dryer ducts. Two switch types can be used in such fans, pressure switches, or a current sensing relay. A pressure switch gives pressure in the dryer duct run, and as a result- it allows power to move to the fan. A current sensing relay senses electricity running to the dryer, and it provides power to move to the fan.

Dryer vent booster fans with pressure switch:

  • Fantech DBF110
  • Fantech DBF4XL
  • Fantech DBF4XLT
  • Tjernlund LB1

With current sensing relay:

  • Suncourt DRY04

What does a dryer vent booster fan do?

When it comes to ducting dryers – the ideal solution is to flow the Dryer Vent Booster Fan system entirely to the wall backing the dryer—a duct flow of maybe 1 foot or less.

The truth which builders and homeowners have to work with is not ideal. A short length of duct is not always available. It is possible if dryer booster fans can help.

Under main conditions, commercial and residential clothes dryers should dry clothing in a well-timed fashion. Issues occur when dryers are attached to a long flow of ductwork. So, it is the reason why most residential dryers are present among outside walls. The drained air is emitted directly to the outside without complex ducting to obstruct the dryer’s performance.

If your duct run increases 25 feet in length – you are possibly an applicant for such a fan. HVAC cleaning in Atlanta, GA, increases its working time and helps to work efficiently.

Based on look over the suggestions from the dryer constructor and local building codes in chosen areas, dryer Dryer Vent Booster Fan is mainly needed when the duct length increases the following:

Maximum duct length:

  • No bends – 25′
  • 1 bend – 20.’
  • Two bends – 15′
  • 3 bends – 10′

Such a fan will assist your dryer run perfectly; your clothes dry fast and saving energy.

Work of a Dryer Booster Fan:

Have you observed that it is taking more time for your dryer to dry your clothes? If yes, your dryer pipe may be blocked. When air is mixed with wetness, it can cause laundry lint to get immoveable on the inside of the dryer pipe. Then, an expansion of lint occurs to form a blockage in the pipe and slow drying time. It creates because you may not clean the pipe yourself, and you may need to engage someone to do it. So, Dryer vent cleaning in Atlanta, GA, helps the dryer to work efficiently.

The main issue with that is the blocking is probably to occur again. Replacement present for it is good news. It can assist your dryer in drying your clothes more perfectly, with less build-up of lint. The result: your clothes will dry more quickly, and you will preserve energy, which is good for you and the planet.

Under better conditions, commercial or residential dryers will dry clothes quickly and keep doing so. However, issues mainly occur when dryers are associated with long runs within the ductwork. The classical residential dryer won’t be able to operate perfectly with excessive resistance from long ductwork. Moreover, many times, the dryer establishment does not permit direct venting in its installation. It results in higher energy costs, more time required for the dryer, and unnecessary wear and tear on the dryer.

Such fans work by increasing airflow between your dryer ducts. Its results are minor lint blockage and can reduce drying times by up to 50%. You can also improve the durability of your dryer. They suggest townhouses and apartments that have rapid firewalls dividing the housing units. Centrally located laundry space in apartment settings is better for a Dryer Vent Booster Fan, while basement laundry areas do not have direct venting. Lastly, even apartment units with the quickest individual laundry encounter will be good from such fans.

Installation:

Installation is simple. Cut the already present duct and connect such a fan right in-line. The units will need 120 volts AC. No other wiring is required since all the commands are built-in. some Dryer Vent Booster Fan have hardwired, and a few of them have power cords (LB and DBF4Xl) and

  • Typical Fantech DBF 110 Installation
  • Tjernlund Installation

If you keep the fan near 15 from the dryer, there is a possibility of wet lint pushing to the Dryer Vent Booster Fan blades. In this situation, mostly suggested the auxiliary DBLT 4W lint trap. Tjernlund LB does not apply it.

For more challenging installations:

If your duct is not reachable, it may be present under a solid slab (yes, it occurs!), for this is mainly suggested using an RVF4XL-DB10 combination. It used the Fantech RVF 4XL wall organized fan with the DB 10 controller (the same controller used in the DBF 110).

  • Fantech RVF4XL-DB10
  • Fantech Lint Trap

However, the installation procedure is the same since the RVF 4XL is organized outside on the wall. Still, the DB 10 can mainly be contained inside, or the installer must give a weather-fixed electrical box (rated NEMA 3R) for the DB 10. It applies the same rules.

Duct material that can use:

Do not use pliable vinyl or rigid PVC pipe – both cannot hold the high temperatures that dryers provide. If possible, do not use flexible ductwork as it may be costly. The costate surface can accumulate lint and limit airflow. The best choice is a stiff aluminium or galvanized pipe. Rigid pipe and installations are fireproof and have smooth walls, so lint is less likely to build up. If you manage your duct in an unconditioned space, be sure to cover it in insulating material. If the duct stays warm, it will be less likely to form distillation and collect lint. Dryer vent cleaning in Atlanta, GA, makes the dryer work longer and dry clothes quickly.

Need a lint trap:

If you are keeping your Dryer Vent Booster Fan nearer than 15 feet from the backward of the dryer – you may need it. A fan near the Dryer Vent Booster Fan may be sufficiently powerful to drag lint into the fan body, which could cause blocking.

Fantech DBLT4 is used in this case. The lint trap should be installed so that it is easily approachable for cleaning. Usually, the DBLT4 is installed in the dryer duct just over the Dryer Vent Booster Fan.

The unique “lint blitzing” design used by Tjernlund LB1 makes blocks improbable, even if the fan is installed near the dryer.
