A-Series Industrial Portable Booths
Large-Format Portable Booths for Industrial Painting and Coating — Same Proven Technology, Bigger Scale
What Are the A-Series Industrial Portable Booths?
The Mobile Work Station® A-Series portable booths are the same productivity-inducing, time-saving pieces of equipment as the standard Mobile Work Station® line — only bigger. Originally developed for a customer in the aerospace manufacturing industry, these models have become popular for aviation maintenance, recreational and specialty vehicle manufacturing, and a variety of other industrial applications.
The A-Series models are complete portable limited finishing workstations that allow you to prep and paint areas of larger equipment wherever needed. Key advantages include a larger 10′ × 10′ × 10′ curtained work area, heavier gauge enclosure supports, an extended-height exhaust assembly (2 feet higher than standard), and caster support extensions for increased stability.

Larger Work Area
10′ × 10′ × 10′ enclosed work area with heavier gauge supports and extended-height exhaust — built for industrial-scale work.
High-Volume Filtration
1-1/2 HP motor with 3,500 CFM airflow. 99.78% efficient on overspray with multi-stage filtration including carbon for VOC removal.
Industrial Grade
Developed for aerospace manufacturing. Built for aviation, specialty vehicles, and industrial painting and coating operations.
American Quality
14-gauge powder-coated steel housing construction. Manufactured, assembled, and tested in Omaha, Nebraska. Heavy-duty crate shipping.
Product Overview
Bigger, Built for Industry
For applications where it’s impractical to move the item being worked on to a fixed paint booth, the A-Series portable booths bring industrial-scale filtration and containment to the work. The larger 10′ × 10′ × 10′ curtained work area accommodates bigger workpieces, while the extended-height exhaust assembly (2 feet higher than standard models) and caster support extensions provide the stability and clearance needed for industrial operations.
Originally developed for aerospace manufacturing, the A-Series has proven equally effective for aviation maintenance, recreational and specialty vehicle manufacturing, and a variety of other industrial painting and coating applications.
Energy Savings Over Fixed Booths
For larger items, the A-Series attached enclosure system is designed to enclose only the area being worked on, rather than the entire item. This provides significant energy savings over a large fixed paint booth that requires larger motors, fans, and heated or cooled make-up air. Combined with the patented non-venting recirculation design, the A-Series keeps conditioned air in your facility while delivering professional-grade filtration.
Direct Drive, Hazardous Location Design
All A-Series models feature the upgraded 1-1/2 HP sealed, maintenance-free UL Listed motor rated for hazardous locations. The direct-drive fan assembly eliminates belts, and backward-curved aluminum fan wheels provide non-sparking operation with quiet, efficient performance. Motors can be configured for 115V or 230V single-phase power.

*The caster extensions are centered underneath the filtration housing on models without the attached enclosure system.
The optional Air Monitor, Shut-off, and Alarm System can be added to A-Series models that include the enclosure system (Model No. 5400A & 5410A)
1-1/2 HP Hazardous Location Motor
All A-Series models feature the upgraded 1-1/2 HP sealed, maintenance-free motor — the most powerful option in the Mobile Work Station® lineup. The motor is UL Listed and rated for hazardous locations, meaning it’s specifically designed and certified for use in environments where flammable vapors, gases, or dust may be present.
The direct-drive fan assembly eliminates belts for zero-maintenance operation, and backward-curved aluminum fan wheels provide non-sparking operation with quiet, efficient performance. Motors can be configured for 115V or 230V single-phase power to match your facility’s electrical setup.
3,500 CFM Airflow
CFM (Cubic Feet per Minute) measures the volume of air moving through the unit’s filter set. All A-Series models deliver 3,500 CFM — the maximum airflow available in the Mobile Work Station® product line — providing robust air movement for industrial-scale painting and coating operations.
The multi-stage filtration system achieves 99.78% efficiency on overspray, including activated charcoal and carbon filters for VOC removal. The patented non-venting recirculation design keeps conditioned air in your facility while delivering professional-grade containment and filtration.
Curtain Enclosure System
The A-Series curtain enclosure assembly provides a 10′ × 10′ × 10′ enclosed work area — significantly larger than the standard Mobile Work Station® enclosure. The enclosure features heavier gauge supports for stability and is constructed with soft, double-polished clear flame-resistant .020 PVC that meets NFPA 701 requirements for flame resistance.
The enclosure is designed to enclose only the area being worked on, rather than the entire item — a major advantage when working on larger equipment. Models 5400A and 5410A include the curtain enclosure. Base models (5450A, 5460A) are available without the enclosure for open-air filtration applications.
Fire Suppression System
A dedicated on-board dry chemical fire suppression system is available for A-Series models. The system provides automatic fire detection and suppression within the unit and is recommended for facilities with strict fire safety requirements or insurance mandates.
Models 5460A (without enclosure) and 5410A (with enclosure) include fire suppression as part of their standard configuration. Fire suppression can be combined with the curtain enclosure for maximum safety compliance. Contact us for details.

Frequently Asked Questions
The A-Series uses the same proven technology and patented recirculation design as the standard Mobile Work Station®, but is scaled up for industrial applications. Key differences include: a larger 10′ × 10′ × 10′ curtained work area (vs. standard size), heavier gauge enclosure supports, an extended-height exhaust assembly (2 feet higher), and caster support extensions for increased stability. All A-Series models use the 1-1/2 HP motor/fan assembly for maximum airflow.
The A-Series was originally developed for a customer in aerospace manufacturing and has since become popular across aviation maintenance, recreational and specialty vehicle manufacturing and maintenance, large equipment refinishing, industrial coating operations, and other applications where larger-format portable containment and filtration is needed.
No. Like all Shop-Pro equipment, the A-Series uses a patented non-venting recirculation design. Air is drawn through multi-stage filters and recirculated back into your facility. For larger items the enclosure system is designed to enclose only the area being worked on, rather than the entire item, providing significant energy savings over a large fixed paint booth that requires heated or cooled make-up air.
All A-Series models feature the 1-1/2 HP motor and are commonly set up for 115V power and feature a 20 amp plug. They can be configured for 230V single-phase power if desired. Each unit comes with a heavy duty 30-foot power cord.
Four A-Series models are available, all with the 1-1/2 HP / 3,500 CFM fan/motor assembly: Model 5450A (base filtration unit), Model 5460A (with fire suppression), Model 5400A (with 10’×10’×10′ curtain enclosure), and Model 5410A (with curtain enclosure and fire suppression). All models include caster support extensions for increased stability.
The caster support extensions are included with all A-Series models and provide increased stability for the larger, taller unit. On models without the curtain enclosure, the extensions are centered under the intake housing assembly. On models with the enclosure, the extensions mount extending forward approximately 38 inches in front of the intake to support the larger curtain structure.
Filter maintenance is straightforward thanks to the quick release filter door system, adjustable filter racks, and common sized 20″×20″ filters utilized. The included Magnehelic pressure gauge indicates when filters need replacement by measuring pressure drop across the filter bank. Filter Saver skins extend the life of your primary filters. Replacement filters are available directly from Shop-Pro Equipment through our Supplies page.
The A-Series is generally not recommended for standard passenger vehicles as the additional height is not needed and the caster extensions (approximately 8 1/4″ high) will not roll under some lower profile cars. However, the A-Series is becoming an increasingly popular choice for working on sprinter type vans and recreational vehicles.
