Abrasive Blasting Guns


Style A	Style B	Style C

Foot-Pedal Control


Style A	Style B

Connect to a foot pedal switch (sold separately) so you don’t have to squeeze the trigger to blast. They’re more comfortable to use when blasting for longer periods. They can also be used in systems with a shutoff valve on the air line.

Style A—Replace the nozzle in these guns when it wears out.

Style B—The grip on these guns is shaped to comfortably fit your hand. Replace the nozzle when it wears out.

Precise-Control Handheld Abrasive Blasters

Hold these blasters like a pencil to blast small, delicate parts with precision. They spray an airstream that’s five times smaller than standard handheld blasters, so you can target specific features without spraying surrounding areas. Use them for detailed cleaning and precision etching. They have their own media reservoir—just connect an air source. The reservoir sits above the airstream and feeds media by gravity, so you can only blast while holding the blaster horizontally or slightly downward.

Handheld Abrasive Blasters

Carry these blasters anywhere for small blasting jobs. Use them to clean, etch glass, and remove rust and paint. Unlike abrasive blasting guns, they have their own media reservoir—just connect an air source. The reservoir sits above the airstream and feeds media by gravity. You can only blast while holding the blaster horizontally or slightly downward.

Use them with any abrasive media. They also work for pressure washing with liquids.

Blast at any angle to reach tight spots. These handheld blasters have a suction feed to pull media into the airstream regardless of orientation. Carry them anywhere for small jobs such as cleaning, texturing, etching glass, or removing rust and paint. Just connect an air source—they have a built-in media reservoir.

Use them with any abrasive media. They also work for pressure washing with liquids.

Abrasive Blaster Safety Switches


Handle Actuator Shown in Use	Trigger Actuator Shown in Use

Toggle Switch Actuator Shown in Use

Add these switches to your abrasive blasting hose to prevent it from spraying if the operator loses control. Also known as deadman switches, they prevent injuries and reduce wasted material by springing back to the off position when the operator lets go. All are for use with blasting systems that allow remote control blasting. Attach to your hose with hose clamps.

Electric


Toggle Switch Actuator	Handle Actuator

Trigger Actuator

These switches send an electric signal to the control panel on the blaster to stop the spray. Because the signal is electric, these switches respond quickly even when your hose is long. They're recommended for hose that's over 100-ft. long and required by OSHA standards for hose that's over 200-ft. long.

Toggle Switch Actuator—Mount on top of your hose and control the toggle with your thumb. They’re smaller and lighter than switches with handle and trigger actuators, but harder to use with bulky gloves.

Handle Actuator—Mount these below your hose to grip the switch and hose together. The large surface area provides leverage when squeezing the switch in your palm, even when wearing bulky gloves.

Trigger Actuator—Extra grip allows you to twist and maneuver the hose without straining your wrist. The trigger is simple to squeeze, even when wearing bulky gloves. To prevent accidents, an included secondary safety lock requires two motions to begin blasting.

Air Powered


Handle Actuator	Trigger Actuator

Send an air signal to the blaster’s inlet and outlet valves to stop the spray. These switches are easier to install and maintain than electrical switches. However, signal delay increases with hose length, so these switches are not recommended for hose over 100-ft. long.

Easy-Hold Abrasive Blaster Safety Switches

Shown in Use

Reduce fatigue during long blasting sessions—these switches are built into a holder for your blaster hose. The holder has a brace that adjusts to shift most of the hose’s thrust away from your arms and grip, and repositions for comfort or different blasting angles. Switch easily between right- and left-hand use without having to take it apart. The housing has upper and lower rail mounts for optional accessories such as a side handle or flashlight (both sold separately). The mounts swivel around the clamp to keep accessories steady as the hose twists during blasting.

Also known as deadman switches, these switches stop blasting if you lose control. They automatically spring back to the off position to prevent injuries and reduce wasted material. To avoid accidental activation, a secondary safety lock requires an additional motion to begin blasting.

Light cuts through dust to keep your work visible. These flashlights mount to the front of the rail so light follows your blast stream. Because the rail swivels, the light stays steady as the blast hose twists. A durable housing and a protective lens withstand contact from abrasive ricochet during blasting. When the lens wears, tear it off and replace it without any additional tools.

Dry Ice Blasters

The cleanest, safest way to blast. These blasters turn liquid CO₂ into dry ice pellets that remove paint, grease, and dirt—without releasing harmful abrasive media into the surrounding air. Since the pellets turn to gas on contact, there's no media left behind to clean up.

Ideal for light surface prep on metals, the dry ice pellets won't scratch or etch your material. Adjust the pressure and spray width for small or large surfaces, and fine-tune your settings in real time using feedback from the display. Do a test run before using these blasters on soft plastics, since the pellets may leave behind a texture. Opt for a blasting setup with conventional media for tough removal of heavy coatings, corrosion, or scale.

You don't need to order pellets to get started. The built-in pelletizer converts liquid CO₂ into blasting media as you work. Connect a 50 lb. or 75 lb. CO₂ tank with siphon tubes (sold separately). The system draws CO₂ only when you pull the trigger, so quick jobs won't drain your tank. Any unused CO₂ can be stored for later jobs. Set these blasters up in any well-ventilated space.

Wide Airflow Pattern—Sweep over large areas. These nozzles produce a flat, thin airflow.

Focused Airflow Pattern—Aggressively clean smaller areas. These nozzles produce a tight, concentrated airflow pattern to remove stubborn paint, oil, or soot.

Short—Best for delicate cleaning. These nozzles spray dry ice pellets at a lower velocity.

Long—Ideal for aggressive cleaning. These nozzles spray dry ice at a higher velocity.
