What Is an Air Shower? High-Velocity Particle Removal for Cleanrooms and Tunnels
"Air shower" usually means a walk-through decontamination chamber, but Goodwind's air shower is a different product: an adjustable-nozzle high-velocity jet device for dust and particle removal in cleanrooms and tunnels. Here's what it actually is.
An air shower is a high-velocity air jet device designed to remove dust and particles from a space, most commonly specified for cleanrooms and tunnel applications. Goodwind's air shower (model GT-AS) uses adjustable nozzles that can be set up to 45° to direct air coverage where it's needed, and is available in powder-coated or chrome-plated finishes.
What Is an Air Shower?
The term "air shower" covers more than one type of equipment in the HVAC and cleanroom industry, so it's worth being specific about what Goodwind's version is. It delivers high-velocity air jets through adjustable nozzles, aimed at removing dust and loose particles from a cleanroom or tunnel environment. The nozzles adjust up to 45 degrees, so the direction and spread of the air jets can be set to match the layout of the space rather than firing at a single fixed angle.
Air Shower vs. Air Shower Chamber
Elsewhere in the cleanroom industry, "air shower" often refers to a walk-through decontamination chamber: an enclosed booth with interlocking doors that a person or piece of equipment passes through, getting blasted with jets of air for a few seconds to knock loose particles off before entering a clean area. That's a different product with a different job.
Goodwind's GT-AS is a fixed unit mounted in the space itself, running continuously or on demand to control particles in the room, rather than a one-time entry blast on the way in. If your requirement is a walk-through entry chamber, that's not what this product is. If you need ongoing particle removal inside a cleanroom or tunnel, the GT-AS is built for that.
Why Cleanrooms and Tunnels Use Them
Cleanrooms rely on active particle control, since even small amounts of dust can affect sensitive manufacturing or lab processes running inside them. This kind of control is common in pharmaceutical and electronics cleanrooms, including GMP-regulated facilities and spaces classified to standards like ISO Class 7, where airborne particle counts are held to a defined limit. Tunnels have a related but different problem: moving dust, exhaust particulate, and debris out of a long, enclosed space. In both cases, a jet fixed at one angle only helps the area it happens to be pointed at. Adjustable nozzles let the airflow be aimed at wherever particles are actually collecting, which shifts depending on layout, ventilation direction, and where extraction points sit in the space.
Finishes Available
Goodwind's air shower comes in two finishes. Powder-coated suits general industrial and cleanroom use. Chrome-plated is the option where appearance and resistance to handling wear matter alongside performance. As an air shower manufacturer, Goodwind builds the GT-AS in either finish to match the environment it's going into, and has supplied HVAC air distribution products for projects in the UAE and Bahrain, including the Dilmon Project in Dubai and Nesto in Bahrain.
Frequently Asked Questions
What is an air shower?
Goodwind's air shower is a high-velocity air jet device with adjustable nozzles, used to remove dust and particles from cleanrooms and tunnel environments. It's a different product from the walk-through personnel decontamination chambers that "air shower" sometimes refers to elsewhere in the industry.
Is Goodwind's air shower the same as a walk-through air shower chamber?
No. A walk-through chamber is an enclosed booth people or equipment pass through for a one-time particle blast on entry. Goodwind's GT-AS is a fixed unit that provides ongoing particle control inside the room.
Where are air showers typically used?
In cleanrooms, including pharmaceutical and electronics facilities where particle counts are controlled to standards like ISO Class 7, and in tunnels, where dust and debris need to be moved out of a long enclosed space.
How does the adjustable nozzle work?
The nozzles can be set up to 45 degrees, which changes the direction and spread of the air jet so it can be aimed at where particles are collecting rather than firing at one fixed spot.
What finishes does Goodwind's air shower come in?
Powder-coated and chrome-plated.
