Mobile Work Station® Portable Paint Booth
EPA 6H Certified Compliant Portable Limited Finishing Workstation — Over 30 Years of Proven Performance
What Is the Mobile Work Station® Portable Paint Booth?
The Mobile Work Station® is a portable air filtration system and booth all-in-one, popular for automotive collision repair, aerospace maintenance, manufacturing, and industrial painting applications. Its patented non-venting recirculation design means no building ventilation modifications are required — just plug it in and go to work.
Self-contained, rugged, and mobile, the unit moves to the work rather than requiring the work to come to a fixed booth. Our standard models equipped with the attached enclosure system have been certified EPA 6H compliant for the spray application of paint using our conventional filter set. With its multi-stage filtration achieving 99.78% efficiency on paint overspray and activated carbon filters for VOC and odor removal, the Mobile Work Station® delivers professional-grade results in any facility. Over 30 years of proven service across thousands of installations make it the industry standard in portable painting solutions.

Product Overview
Versatility Built-in
The Mobile Work Station® portable paint booth is the most versatile portable booth on the market. Its patented non-venting recirculation design and self-contained construction create a complete paint spray environment virtually anywhere in your facility. The unit requires less than 3 feet of aisle space for mobility and can be repositioned as workflow demands change.
Originally designed for automotive collision repair, the Mobile Work Station® is now used across a broad range of industries including aerospace, automotive, manufacturing, woodworking, building maintenance, defense, energy, and education. Its versatility comes from the adjustable filter rack system — swap filter sets to match your specific application, from paint spraying to sanding to welding fume extraction.
Direct Drive, Hazardous Location Design
Every Mobile Work Station® features maintenance-free sealed UL Listed motors rated for hazardous locations. The direct-drive fan assembly eliminates belts, reducing maintenance and downtime. Backward-curved aluminum fan wheels provide non-sparking operation and are statically and dynamically balanced for maximum efficiency and quiet operation.
Resource Protection
The recirculating design delivers significant energy savings by keeping conditioned air inside your facility. No heated or cooled air is exhausted — a major cost advantage over traditional fixed booths. This portable limited finishing workstation(1) mitigates overspray spread, reducing cleanup costs and protecting adjacent equipment. Multi-stage filtration including activated carbon removes VOCs and odors, improving employee health and workplace air quality.
(1) The term Limited Finishing Workstation is found in the National Fire Protection Association’s Standard for Spray Application Using Flammable or Combustible Materials (NFPA 33). By nature, or at least practical design, a portable paint booth (more accurately a paint spray booth or spray booth) will not be designed to meet all the vigorous requirements of a fixed unlimited volume spray booth; and generally will be limited in both usage and size. Thus a more accurate description for equipment commonly knownn as a portable paint booth would be a portable limited finishing workstation.

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* plug. The 1-1/2 HP motor (54 Series) delivers 3,500 CFM for higher-volume applications and is provided with a 20-amp* 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.
*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 smaller workpieces, touch-up work, airbrush, and lighter-volume applications
- 54 Series (1-1/2 HP): 3,500 CFM — advantageous for higher-volume spraying, for use with water-based compounds, and applications where higher volume airflow is desired
CFM is stated as measured using our conventional filter set. Actual airflow may vary with alternative filter configurations.
Curtain Enclosure System
The attached curtain enclosure system converts the filtration unit into a complete filtration/containment booth maximizing the functional airflow pattern. Standard models are certified EPA 6H compliant for paint spray application. Curtains are made from durable, 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 are available without the curtain enclosure for applications that only require the filtration unit.
Fire Suppression System
An optional fire suppression system is available for all Mobile Work Station® models. 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 4910, 4920, 5410 and 5420 include fire suppression as part of their standard configuration. For models 4900 and 5400, fire suppression can be added as a factory option. Contact us for details on fire suppression configurations.
Air Monitor, Shut-Off & Alarm System
Models 4920 and 5420 include an integrated air monitoring system that continuously tests the air quality within the booth. If contaminant levels exceed manufacturer preset safety thresholds, the system automatically shuts down air supply to spray operations and activates an audible and visual alarm, providing an extra layer of safety for operators.
The Air Monitor, Shut-off, and Alarm System is designed specifically for use with the Mobile Work Station® and its attached enclosure system.
