A return air grill connects to ductwork that allows air to return to any cooling or heating system. The openings that connect to ducts and other spaces for the returning air are normally covered with grillwork.

Every cooling or heating system will have air being pushed though into rooms and spaces through a system of ducts. This increases the air pressure in the conditioned area and at some time will act to even prevent any further air from entering unless a circulating system is set up to relieve the pressure. This is done normally through return ducts which allow the air to be recirculated or completely vented to the outside in certain cases. A return air grill will cover such ducts, and can also act to regulate the flow of air. They also act to close off the ducts from view. A return air grill also has a filter mounted on it to trap particulate matter and thus ensure that the recirculated air is more pure. This can also in the long run reduce the amount of cleaning required for ducts.

Ducts for returning air are located at floor level or in the walls depending on the design of the system.  These require to be covered by a  grill that will ensure that duct is  protected. It is considered very necessary to use filters over such grills, which in turn can lead to higher efficiency in cooling or heating. The filters in a way also help to reduce air flow and thus help improve efficiency. Such filters can have increased ratings which in turn can reduce allergens and dust and thus make the circulated air more healthy. A return air grill looks very much like the supply side grills and can only be detected with the direction of the air flow in front of the grill. It is necessary that the space around such grills be kept free of any obstruction, as this can affect the entire system. As a matter of fact, it is best to ensure that all grills, whether supply or return, are kept clear and allowed to function as they are designed.

A return air grill and its filter needs to maintained and cleaned at least once every quarter. Such cleaning can also lead to a system functioning with less noise, as a clogged filter can increase the noise level, because of the greater strain placed on the blowers and fans.

Our Manufacturing Plant Located in Meridian Idaho, USA

Started in 1989, FAMCO has build a tradition of building the best ventilation products available in the world.  They are made in the USA, and made to last.   Our products are available to purchase through our safe and secure website 24/7, by phone during our normal business hours.

Buying cheap imitations, and poorly constructed alternatives may be a no brainer for some contractors or vendors, but we believe that supporting our own U.S. Economy matters.  We manufacture the highest quality products in this industry, and we are committed to keeping our manufacturing on US soil, creating jobs, and helping to re-build the economy.

You many have read that over 5.5 million manufacturing jobs have been lost in the last decade, causing millions more to be lost as a result.  According to the Economic policy Institute, from 1993 to 2003, the US-Mexico trade balance went from a positive 4.9 billion, to a negative 40.6 deficit.

It seems that every day the news outlets report that more and more people are losing their jobs, and many who have jobs, are unsure of the future.  The more workers and businesses that stay committed to keeping their money cycling through our own US economy will be one of the major factors in how soon our economy rebounds.

We many not offer prices as low as the off shore low quality products, but we can offer better quality, service, and durability, at competitive prices.   Help protect our jobs, security, economy, and our communities, by buying products made in the USA.
