Portable Sandblasting Equipment

Air Supplied Helmet
Affords use with full comfort and protection against abrasive ricochet and dust. Bears NIOSH approval number TC-19C-84. Helmets of this design are necessary for operations in blast cleaning rooms, inside of tanks and other confined areas and are required on many open-air operations of heavy duty and lengthy work periods to meet OSHA standards.

Made of refined, one-piece molded high-density polyethylene with special coated nylon cape for durability. Adjustable dihedral headband suspension affords user sizing range comfort. Hinged gasket-sealed vision frame affords maximum vision range with easy change of vision lens. Supplied with S-46-4 HP belt and brake valve assembly.

Compressed Air Line Filter Assembly
Type “A” Air Line Filter Assembly provides clean breathing air to the user because it removes dusts, moisture, oil, fumes and scale from compressed air. Meets ASME Code requirements. Its component compounds are entirely separate from the water and oil condensation changer to prolong the life of the replaceable filtering compound unit. Type “A” Air Line Filter Assembly is recommended for all air supplied helmets and has a capacity to afford clean breathing air to as many as six helmets.

Caution: Compressed Air Line Filters do not remove carbon monoxide.

Venturi Blast Nozzles
The Venturi suction system allows high velocity air pressure to pass over the abrasive feeder line, which sucks the abrasive through the smaller hose and combines it with air pressure at the back of a nozzle. The gun nozzle is a tapered smaller orifice that speeds up the combined flow and sprays out the abrasive in a relatively narrow or fixed pattern of discharge. The SLV Series Nozzles are our latest design of high production blast nozzles. These nozzles are manufactured with a one-piece sintered tungsten carbide liner for extended production life. The liner also allows for slow and even wear throughout the life of the nozzle. A new combination of aluminum and polyurethane adds proven advantages in weight balance, strength and shock absorbent features not found in metal cased nozzles. The long venture design will maximize production requirements as well as give added abrasive impact when needed for tough, hard to clean surfaces.

Oil-less Air Pumps
Oil-less air pumps are available for one or more operators with electric motor or air-driven power. Air pumps are designed for MSHA and NIOSH approved air supplied helmets that operated less than 1 PSIG Ref: S-77-FA and 1094-35. The air pump’s inlet must be placed in a clean, breathable location. The air pump will not remove carbon monoxide or toxic gases from incoming air pumps to the helmets.
EDP-10 available in ³/4" HP model
EDP-16 available in 1¹/2" HP model

Carbon Monoxide Monitor
The ISA-34RAL respiratory air line CO Monitor/Alarm automatically and continuously monitors respiratory air lines for carbon monoxide levels and provides audible and visual alarms when the air line CO concentration rises above a preset limit. When the level of CO in the air passing the sensor increases to the preset value, the equipment alarms and relays activate. The preset calibration level may be as low as 20 PPM. The equipment operates from either 117 VAC or 12 VDC, at the option of the user, with terminals for either mode of operation located on a barrier strip inside the unit. Due to its electronic voltage regulation, the ISA-34RAL maintains precision gas calibration despite input voltage variations as great as –10% to +20% of rated supply (either AC or DC).

Machine Depressurization System
Places complete on-off control machine in hands of operator at blast nozzle. Provides added safety to the operator and others because the machine is automatically depressurized if the operator loses control of the blast hose. Reduces abrasive consumption when the operator changes position or is performing spot blasting work, because the operator can start or stop the abrasive blast at will. A machine depressurization system makes blasting economical and practical for safe one-man operation. Serves as a signaling device between operator and helper when blasting tank interiors, and other confined areas or when operator works out of helper’s sight. Delivers “fail safe” remote control performance because the blast machine will not operate in the event either or both control hoses are accidentally crushed, pinched or severed.
