How Does A Makeup Air System For A Paint Spray Booth Work

During spray jobs in a paint berth, the exhaust system must draw substantial quantities of air out of the shop in gild to operate. These volumes must exist replenished with equal volumes of air coming into the berth.

AIR Make-UP (AMU) is defined as…a mechanical ways of replacing air that has been wearied out of the berth.

It's simple…. information technology'due south all about paint booth air flow. How much air in existence put into the booth and how much is being taken out. Airflow while spraying takes the over-spray away from the pigment chore and out of the berth.

Air in – Air out. Air in – Air out. Air in – Air out. Air in – Air out. That'due south information technology. With the Sure-Cure Air Makeup Unit, you control the amount of air pushed into your berth. Why would yous need to button air into your booth?

NEGATIVE AND POSITIVE BOOTH PRESSURE
When the exhaust fan of the booth is turned on, it creates a "negative" air pressure level in the booth cabin (taking out more than air than is being put in). When there is a negative air pressure, the berth will try to suck in every bit much air as possible, including clay and debris from exterior the booth. THINK VACUUM CLEANERS.

To counter this "negative" pressure level, an Air Makeup Unit of measurement (AMU) unit is used to supply air to supercede the air being exhausted. If the AMU is designed to force more air into the booth than is exhausted…the berth is said to have "positive" air pressure. In this case, the booth has more than air than outside the booth and when a door is opened, dirt and debris is pushed away from the booth. Remember STANDING IN FRONT OF A FAN.

Controlling the pigment berth air flow going into the booth, with relation to the air beingness exhausted from the booth, is critically important to maintain the proper menstruation of air over the item being painted and remove the over-spray effectively.

FANS TO Button AND PULL
The air being pushed in and pulled out are done with ii types of fans. The exhaust fan that PULLS the air out of the Standard Tool's pigment booths is a tube-centric exhaust fan. It is a propeller blade blazon fan. Tube-axial is the all-time fan to exist used on the exhaust of the booth because they are designed to pull the air. Aluminum blades are used because they will not spark, causing a fire, which is important when working with flammable coatings.

The fan that PUSHES the air into the booth through the Certain-Cure AMU is a blower fan, designed to force the air into the berth.

PAINT BOOTH AIR FLOW
Controlling the air flow and pressure is a delicate residuum betwixt input air and wearied air.

When a booth is balanced, it means that the aforementioned corporeality of air is pushed in and pulled out (8,000 CFMs wearied out and 8,000 CFMs pushed in through the AMU). If the painter opens the booth door, the pressure level goes negative and sucks in dirt and contamination thru the open door, and all the other cracks and crevices of the booth.

When at that place is more air being pushed in than sucked out, you create positive force per unit area, so a slight corporeality of air is pushed out when the berth door is open. Positive pressure creates a cleaner booth.

Beingness able to control the airflow changes the way you paint. The Certain-Cure AMU from Standard Tools and Equipment allows you to adjust temperatures, times and booth pressure by means of the energy-saving variable frequency bulldoze contained in the control panel. How practise y'all know if you need makeup air?

WHAT AFFECTS Pigment Booth AIR FLOW?
Full Filters: Paint Booth air flow is afflicted when the exhaust filters become total with over-spray. As the filters fill up upwardly with over-spray, the exhaust fan must work harder to remove the air through those filters and out of the berth. With the aforementioned amount of air beingness pushed into the booth, but at present a lower CFM being pulled through clogged air filters, the booth is over-pressurized. Over-pressurization causes dirt contamination in the booth considering it severely disrupts the designed airflow and causes uncontrolled turbulence.

Adding an particular within the berth: The booth pressure is different empty than when yous have something in the booth to be painted. The item in the booth takes up a certain amount of volume in the booth. Y'all must account for this. If you continue to force the aforementioned amount of air into a berth, which now has a reduced book, you volition over-pressurize the berth (forcing too much air into the berth).

More Nigh THE SURE-CURE AIR MAKEUP UNIT (AMU)

Now that you know how airflow consequence the pigment berth and the spray job, let me tell you lot a picayune bit more than near the Sure-Cure AMU manufactured by us, a leading pigment booth manufacturer… right hither in Greensboro, NC. Y'all can as well read this blog when we outset introduced the Sure-Cure.

We designed the Certain-Cure AMU to optimize booth efficiency, safety and operator comfort through precision controlled heat circulation. Our white pulverisation-coated, ETL-listed units are available for both indoor and outdoor applications, either vertical or horizontal configurations, and tin exist retrofitted to fit any existing booth set up-up.

Spray, flash, cure, and absurd downwards … all in the pigment berth. The Certain-Cure AMU has an automatic shutoff that allows y'all to paint information technology and walk away while it cures, increasing your product to at least two more projects a day (right before your lunch break and right before yous go home).

HOW MANY CFM'S DO I NEED?

We can help yous to determine how many CFM'south you lot need…. but here is a simple equation based on the model booth from the Standard Tools engineers to help y'all get started:

On the Cantankerous Flow, Semi Down Typhoon or the Open Face Booth:

Width of Booth (in feet) X Tiptop of Berth (in anxiety) Ten 100

On the Side Down Draft Booth:

Width of Booth (in feet) X Height of Booth (in feet) X 40

Perhaps you already take an AMU, just thinking you may need to supervene upon it. Hither'due south how you know if you should.
