Product Overview
Versatile Air Filtration
The Mobile Prep Station is the most versatile and flexible prep station on the market. Its patented non-venting recirculation design means you eliminate the need for costly ventilation modifications or air make-up systems — just plug it in and go to work. By using filtered, recirculated air, you reduce energy costs by utilizing your shop’s existing heated or cooled air.
Developed in collaboration with automotive refinishing professionals, the Mobile Prep Station is now used across a broad range of industries including aerospace, automotive, manufacturing, woodworking, defense, energy, education, building maintenance, and more. Its adjustable filter racks let you customize filter combinations for different types and levels of filtration — from paint spraying to sanding to fume extraction.
Cleaner Air, Better Results
High volume performance coupled with the multi-stage filtration of our conventional filter set provides two banks of filters for dust, overspray, and particulates, plus two banks of carbon filters for odors and VOCs and delivers 99.78% efficiency on paint overspray. Removing airborne particles at the source increases productivity by reducing rework and clean-up while providing a healthier work environment for employees.
EPA 6H Compliance
Models equipped with the attached curtain enclosure system have been certified EPA 6H compliant for paint spray application using our conventional filter set. When used with its drapery system, the Mobile Prep Station provides a clean, enclosed atmosphere — anywhere in your shop. A signed Certificate of EPA 6H Compliance is provided with each qualifying unit.
Flexibility is Built In
The exhaust hood can be mounted to face any of four directions to direct airflow where desired. They can be used to filter and recirculate air within an area, exhaust filtered air from an area, supply filtered air to an area, or used in combination to provide a desired filtered airflow pattern.

Motor Horsepower Options
Two motor options are available to match your application needs. The 3/4 HP motor (49 Series) delivers 2,400 CFM and features a standard 15-amp(1) plug. The 1-1/2 HP motor (54 Series) delivers 3,500 CFM for higher-volume applications and is provided with a 20-amp(1) plug. Both motors are sealed, maintenance-free, and UL Listed for hazardous locations.
All motors feature direct-drive fan assemblies — no belts to replace or maintain. Backward-curved aluminum fan wheels provide non-sparking operation and are statically and dynamically balanced for quiet, efficient performance.
(1) Commonly set up for 115V power; can be set up for 230V single phase power if desired. Alternative power options can be accommodated.
System CFM (Cubic Feet per Minute)
CFM measures the volume of air the unit moves through its filter system per minute. Higher CFM means faster air exchange and more effective capture of overspray, fumes, and particulates.
- 49 Series (3/4 HP): 2,400 CFM — ideal for prep work, touch-ups, airbrush, and lighter-volume applications
- 54 Series (1-1/2 HP): 3,500 CFM — advantageous for heavier materials, higher-volume usage, for use with water-based compounds, and applications where higher volume airflow is desired.
CFM is measured through the unit’s standard filter set. Actual airflow may vary with alternative filter configurations.
Curtain Enclosure System
The optional attached curtain enclosure system converts the Mobile Prep Station into a certified EPA 6H compliant portable limited finishing workstation. Curtains are made from soft, double-polished clear flame-resistant .020 PVC that enhances visibility and versatility. The flexible material won’t scratch work surfaces. All curtains meet NFPA 701 requirements for flame resistance.
The enclosure creates a contained work area that captures overspray at the source, dramatically improving air quality in the surrounding facility. Models 4900 and 5400 include the curtain enclosure. Base models (4950, 5450) are available without the enclosure for open-air filtration applications such as sanding, buffing, and priming.
Fire Suppression System
An optional on-board dry chemical fire suppression system is available for the Mobile Prep Station. The system is installed at the factory by an authorized distributor and provides automatic fire detection and extinguishing system covering the fan, filters, ducting, and plenums. This option is recommended for use where protection against combustible dust and VOC’s is desired.
Models 4960 and 5460 include fire suppression as part of their standard configuration. Contact us for details on fire suppression configurations.
