The PDB comes as a Downdraft or Backdraft Collector. It is designed for odor elimination from spray paint and mold release overspray.
In dust collection, the concept of dialing back the CFM for better VOC scrubbing may seem counterintuitive. Unlike particulate matter where high capture velocity is crucial for swift filtration, VOC demands a different approach. Using an oversized motor and blower can lead to rapid passage of VOC through the absorption media, compromising effectiveness. We pinpoint the optimal settings. This tailored approach ensures not only maximum dwell time in the carbon, but also efficient and trouble-free operation.
Paint fumes from spraying of small machine parts eventually makes its way into the HVAC system. Then you are stuck with the odor and nasty VOC.
Our collection system has a 20 year track record of fixing this problem with careful configuration of different filter stages.
Spray painting small parts VOC capture is accomplished by looking at the size of the piece being sprayed, and how far away from the table-top grates will you be spraying. Sometimes a Backdraft will work better. Each application is different. We take everything into consideration and we come up with a solution that incorporates high capture velocities of over 300 FPM with the right filtration, and safety components. By doing this, the end user has the most functionality with the highest degree of clean air and efficiency.

PDB-VOC Booths are 30" W x 24" D and 48" W x 24" D , designed to capture and filter overspray paint while returning clean air into the work space. The PDB can eliminate 90% of odors and Volatile Organic Compounds (VOCs). The custom blend of filtration makes it extremely useful and adaptable for all kinds of applications.
Explosion-Proof Motor and NEMA 7/9 Starter is optioned with every unit. Certifications and specifications for the motor and starter are available with each quote we send out.
A custom blend of activated carbon pellets and potassium permanganate pellets is used to eliminate odors. The PDB is designed to extract VOC fumes and odors directly from the source and prevent them from entering an operator’s breathing zone. Having the right amount of “dwell-time” of the VOC within the carbon is essential to the success of the unit. Our sales engineers will analyze your solvents SDS and we will recommend either carbon, pellets, potassium permanganate, coconut shell, or a custom blend. Then we select the correct blower size designed to achieve optimum dwell-time.

Source capture stops odors from migrating to office areas. Once the fumes are created they are stopped at the source before they can travel anywhere.
Normal cartridge filters plug up from paint spray in a matter of seconds. The PDB-VOC has a custom blend of fiberglass Rigid Cell, Poly Pad, and 4mm carbon or potassium permanganate cells. Each cell holds 28 lbs. and the PDB can hold 3 of them. This blend of filtration will do a much better job on heavy odor and sticky fumes and odors than particulate filters will.
