Overview · Advantages · Room Styles · How the Blast Room Works · Features · Options · WARNING




Starch, plastic, and abrasive media blast operations require a controlled environment. A safe, self-contained and highly productive multi-media blast room that does not pose a health threat to workers or a toxic hazard to the environment as is caused by liquid chemical paint stripping. Nor does it contaminate the factory, hangar or workplace with noise and dust. A room with generous lighting and ventilation for maximum Operator comfort and optimum work performance. Where media is cost effectively reclaimed and reused, not wasted as it is by other systems.

Pauli Systems’ Reclaimable Abrasive Machine (RAM™) Blast Rooms give you all this plus a whole lot of additional built-in features. Just look at our long list of standard features on the RAM Blast Room features below.

Dry paint stripping


PMB (Plastic Media Blast) or Starch Media Blast



Engineering for starch and plastic media yields outstanding multi-media performance:

The performance advantages found in the RAM Abrasive Blast Room have roots in the most demanding conditions - dry media blasting with starch and plastic. In designing our media blasting room, we’ve built-in new and advanced engineering techniques like straight through media valves for non pulsing media flow. Dual control variable particle size reclaimer. Media aeration. Brilliant lighting. And 60 degree angles on all hoppers, engineering which translates into enhanced power and smooth, responsive performance. Qualities that are every bit as essential to Operators blasting with conventional abrasives as they are to Operators using starch and plastic media.

Cost savings are exceptional:

You can reuse media over and over because your blast room is equipped with a RAM System, the world’s most preferred blast and reclaim system. RAM uses a pneumatic conveying system to carry spent media to a four stage recovery and reclaim process: a cyclone centrifuge, dual adjustable air wash, magnetic separator and a vibratory screen. These combine to separate dust, debris and contaminants from reusable media. In addition, a dense particle separator option, the DPS 3000, is available at extra cost to meet aircraft manufacturer and military specifications for media cleanliness in critical applications.

Brilliant lighting for optimum productivity:

No other blast rooms offer such brilliant illumination. Exceeding the highest military specifications for blast room lighting, our rooms enable Operators to work more productively on routine as well as detailed jobs. 120 to 150 footcandle lighting level in midroom, while blasting with plastic and starch media, provides exceptional light for exceptional performance. Results of USAF testing. Documentation available.

The multi-media machine:

Designed with advanced media flow engineering principles, RAM Abrasive Blast Rooms have roots in high performance starch and plastic media blasting. Engineering which provides smooth, responsive plastic and starch media blasting in addition to a new level of conventional abrasive blasting performance that Operators will find outstanding. That’s why you can use aluminum oxide, glass beads, starch, plastic and virtually any blasting media with excellent results. Never use Pauli Systems equipment and/or parts with sand.

The multi-media Air Force blast room:

The US Air Force requested two blast room systems – conventional abrasive and plastic media. A single, high-performance multi-media blast room was engineered to exceed all specifications. We won the contract and created our first New Generation Multi-Media Blast Room. Because of this state-of- the-art performance the USAF ordered over 150 rooms.

Lo-Pro Feathertouch® remote control lightens the workload:

Lo-Pro Feathertouch, our remote blast control, is faster, more reliable, and more convenient than any other blast controller. The compact design enables exceptional blast control for the most sensitive operation. Even in its open position as shown in the photograph, the Lo-Pro Feather-touch, combined with our extra flexible blast hose, gives Operators the smallest, most comfortable and most productive ‘handful’ in the industry.
Blast Rooms

AutoClean dust collector provides super ventilation for maximum productivity:

A continuous rush of air sweeps through the Abrasive Blast Room and makes working on detailed parts a breeze. In fact, government tests proved our most popular rooms’ airflow average is far in excess of our nominal specifications of 67-70 feet per minute (20.4-21.3 m/min). Dust laden air is carried to a dust collector filter of cartridge design. The dust collector is a 100% duty cycle unit with cartridge cleaning via reverse air jet pulses activated automatically by a solid state controller.
Blast Room

Powered by RAM, the industry’s top recovery, reclaim and blast package:

Rugged, reliable, and revolutionary, RAM is specifically designed to efficiently blast, recover and reclaim plastic and starch media and provide outstanding performance with conventional abrasive media.
All floor hoppers, pressure vessel bottoms and dust collector hoppers have slopes of 60 degrees from horizontal for complete discharge of plastic, starch and other media. A pneumatic conveying system carries spent media to a cyclone centrifuge, dual adjustable air wash, vibrating screen and magnetic separator which rapidly separates reusable abrasive from dust and debris. 24 cubic feet (0.68m³) of media in the storage hopper and pressure vessel expand blasting time substantially before reclaiming

Optional AccuFlow® empowers Blast Rooms:

We powered-up our RAM Abrasive Blast Room with AccuFlow technology to give you a high production environment that surpasses anything in the industry. AccuFlow’s computerized media control technology enables smooth, repeatable media flow that your Blast Operators will find remarkable - and quality of work you’ll find outstanding.

The Smart Panel stays alert while you work:

A Smart Panel control station on the Abrasive Blast Room exterior wall is the watchdog for the unit’s key functions - dust collector blower, door interlocks, recovery booster blower, and room lights. Status lights show function ‘on’ and ‘off’ conditions. To maximize Operator safety, the panel includes a carbon monoxide monitor, alarm, display meter and 3 status lights.

RAM DPS 3000 high volume Dense Particle Seperator:

The DPS 3000 allows you to separate and remove dense particles from plastic and starch blast media to meet US Military and aircraft OEM specifications for media cleanliness. The system separates dense particles such as sand, metallic particles, and other dense debris and drops them into a collection bin.

Operator training:

Thoroughly trained Operators not only do work properly and without damage but do it in less time than untrained operators.
That’s why Pauli Systems offers the highly respected Total Technology Transfer training and certification program. Students have classroom instruction, written exams and hands-on experience enabling them to pass rigid certification requirements. Training can be conducted on location.

Room Styles


Pneumatic Systems - The Full Recovery Floor Room

The Full Recovery Floor Room
offers a complete active floor that recovers media while blasting. Each floor trough is emptied sequentially by a Pauli Systems' designed indexing selector unit. Automatic recovery frees the operator from sweeping and reduces cleanup and media recovery man-hours.

Pneumatic Systems - The Partial Floor Room

The Partial Floor Room
uses a single trough, normally placed in the center of the floor, into which the Operator sweeps spent media. This model can be fitted with two or more troughs to fit your application.
Abrasive Blast Room Media Recovery

Pneumatic Systems - The Lo Profile Hopper Room

The Lo Profile Hopper Room
is the most economical and easy to relocate. Simple to install and dismantle, it uses a revolutionary hopper that allows easy sweep-in recovery-without the need to cut into an existing floor.

Mechanical Systems

Mechanical Screw Recovery System
is perfect for steel and other metal media. It automatically recovers media while blasting, frees the operator from sweeping and reduces clean-up time.

How the Abrasive Blast Room Works

The Operator brings the workpiece into the room through the large convenient double doors. Then wearing protective clothing including an approved blasting hood supplied with approved respirable air, the Operator activates the process by selecting safety button off and depressing the lever of the Feathertouch remote control. The process will not start unless the Operator has shut all doors and turned on the key functions.

Dry paint stripping involves the Operator holding a nozzle and directing its low-pressure stream of media at a workpiece until its coating or contaminants are stripped away by impact and abrasion. Throughout the process, a powerful ventilator pulls a continuous stream of air through the room, removing airborne dust. The Operator’s job is made easier and safer by the intense illumination that floods the work area.

After the stripping is over - or simultaneously with it, depending upon the blast room floor model - a pneumatic conveying system carries the spent media to the cyclone centrifuge, dual adjustable air wash, vibratory screen and magnetic separator which cleans the media and returns it to the system for reuse. The reclaimer discards spent media and debris in a dust collector and upon vibratory screens.

When blasting with conventional abrasives such as glass beads and aluminum oxide, the concept is similar but the process is more aggressive because of media characteristics and generally higher nozzle pressure. With Pauli Systems, switching to another abrasive is simple - merely readjust the variable density reclaimer
