The blast industry's most popular and comfortable respirator, the Apollo 60 features double-shell construction, sound-deadening foam, and large window. The Apollo 60 is NIOSH-approved, and protects against lead dust at concentrations 1000 times greater than the permissible exposure limit.

Air fed helmets are critical in a blasting environment. The helmets offered by Clemco are approved by the Health & Safety Executive and are CE marked as required by European Law.

The air conditioning unit allows the blast operator to cool or warm the incoming compressed air to a Clemco high-pressure Type CE continuous flow supplied-air helmet/respirator.

Requirements for Operation

20 cfm at 90 to 100 psi of Grade D quality breathing air as defined by the Compressed Gas Association Commodity Specification: G-7.1 (www.cganet.com)

Pressure requirements vary with hose length.

• 25 ft – 75 ft 90 psi
• 100 ft – 125 ft 95 psi
• 150 – 200 ft 100 psi

NOTE: Do not exceed 200 ft of respirator hose with this device.

Advantages

• Helps increase productivity by keeping blast operator cool in hot weather and warm in cold weather
• Durable construction
• Lightweight comfort system maintains NIOSH approval
• Certifications and Approvals

• The air conditioning unit is approved by NIOSH for use only with Clemco Apollo HP high-pressure Type CE supplied-air respirators (not for use with low-pressure respirators).
• The air conditioning unit is one component of a NIOSH-approved system; use of counterfeit parts voids the NIOSH approval.
• To maintain NIOSH approval, use only genuine Clemco Apollo replacement parts.

Clemco Supa blast hose is standard equipment on all Contractor Series Blast Machines. Supa hose is lighter and more flexible than 2-braid or 4-ply blast hose of the same ID. It can be used with all common blast media. Supa hose achieves its lightness and flexibility from its slightly thinner outer casing. The inner tube is made from SBR rubber.

Description of Operation

Clemco Supa blast hose is fabricated to fit Clemco couplings and nozzle holders. The blast hose inner diameter (ID) should be 3 to 4 times the size of the nozzle orifice and the same size as the nozzle entry diameter. The hose ID should be the same size or larger than the machine piping.

For applications where heavier 2-braid or 4-ply blast are used (for their more durable outer casing) a 10 to 15 foot length of Supa hose can be connected as the last section before the nozzle. This whip hose is easier for the operator to maneuver.

Advantages

• Inner tube wall of SBR rubber treated with static-dissipating compound
• Reinforced outer casing of cloth and rubber-impregnated fiber winding
• Casing is pin-pricked to prevent formation of air pockets between layers
• More flexible than 2-braid or 4-ply blast hose
• Lighter weight and slightly smaller OD make it a better whip hose

The Clemco fiber-reinforced nylon nozzle holder attaches to the end of a blast hose and holds a contractor-thread blast nozzle.

Description of Operation

The blast hose must be cut squarely and cleanly. The nozzle holder is installed with the screws provided. These screws penetrate the outer wall, but not the inner wall of the blast hose.

In operation, the air pressure inside the blast hose helps hold the nozzle holder securely in place.

A nozzle washer must be placed on the shoulder inside the nozzle holder to prevent premature wear and failure, of both the holder and the nozzle, from high-speed abrasive.

NHP-3/4 fits 3/4-inch ID Supa hose
NHP-1 fits 3/4-inch ID 2-braid hose, (1-1/2-inch OD) and 1-inch ID Supa hose
NHP-2 fits 1-inch ID 2-braid and 4-ply blast hose (1-7/8-inch OD) and 1-1/4-inch ID Supa hose
NHP-3 fits 1-1/4-inch ID 2-braid and 4-ply blast hose (2-5/32-inch OD)

Advantages

• Fiber-reinforced nylon material springs back from most impacts that would dent or deform metal nozzle holders
• Lighter weight than metal nozzle holders
• Precision dimensions
• Large thread makes changing nozzle easy

A blast nozzle accelerates the air and abrasive as the mixture exits the end of the hose. The taper and length of the nozzle’s inlet and outlet determine the pattern and velocity of the abrasive exiting the nozzle. The composition of the liner material determines its resistance to wear.

Requirements for Operation

Nozzles are sized by the diameter of their orifices in 1/16-inch increments. A No. 2 nozzle has a 2/16-inch (1/8-inch) orifice, a No. 3 nozzle has a 3/16-inch orifice, etc. The size of the nozzle orifice determines abrasive and air consumption. Air consumption is measured in cubic feet per minute (cfm) at a given pressure.

When choosing a nozzle, consider the amount of available air in cfm, the capacity of the blast machine and the inside diameter of the piping, and the blast and air hoses. For optimal performance, these elements must be compatibly sized.

If too large a nozzle is used, low blast pressure and rapid wear on the blast hose will occur. If too small a nozzle is used, smooth media flow will be difficult to achieve.

Description of Operation

The operator inserts the nozzle washer into a contractor-thread nozzle holder and screws in the nozzle, turning it by hand, until it seats firmly against the washer.

With all related equipment correctly assembled and tested, the operator points the nozzle at the surface to be cleaned and presses the remote control handle to begin blasting. The operator holds the nozzle 18 to 36 inches from the surface and moves it smoothly at a rate that produces the desired cleanliness. Each pass should overlap slightly.

The operator must replace the nozzle once the orifice wears 1/16-inch beyond its original size.

Advantages

• Expected life with expendable abrasives is up to 500 hours
• Durable urethane jacket
• Non-binding contractor threads
• 42% lighter than tungsten carbide

The Clemco fiber-reinforced nylon quick couplings attach to blast hose to facilitate connecting blast hose to blast machine, blast hose to blast hose, and blast hose to quick-coupling nozzle holders.

Description of Operation

Clemco nylon quick couplings attach to the end of any properly sized blast hose using screws provided. The hose must be cut squarely and cleanly. The screws should penetrate the outer layer of the blast hose without perforating the inner tube. In operation, air pressure inside the blast hose helps hold the hose tight against spiral ribs inside the coupling. Using a quarter turn, the blast operator connects the quick coupling to any other quick coupling or quick coupling nozzle holder. A built-in lock-spring on the coupling keeps the couplings securely connected. All blast hose coupling connections should be secured with safety cables.

Advantages

• Fiber-reinforced nylon material springs back from most impacts that would dent or deform metal couplings
• Built-in lock-springs eliminate need for safety pins
• Lighter weight than metal couplings
• Injection molded for precise dimensions, ensuring positive fit

Clemco's CPF in-line air filters remove moisture, oil, and dirt particles from compressed air before it reaches your respirator. Multi-stage filtration system includes activated charcoal to eliminate odors and improve the “taste” of your breathing air. Available for one to four air lines; used with HP Model respirators.

NOTE:CPF filters do not remove CO or convert CO to CO2, or remove other toxic gases.

Requirements for Operation

Compressed Grade D quality breathing air as defined by the Compressed Gas Association commodity specification: G-7.1 (www.cganet.com).

Description of Operation

The CPF filter is placed in the breathing-air line between the breathing-air source and the respirator supply hose.

The CPF is the point of attachment for the respirator hose. Air enters the filter through one of the inlet ports. Moisture is removed by expansion in the outer chamber and is drained through a petcock at the bottom of the unit. The air passes through a replaceable filter cartridge. The outlet pressure is controlled by a regulator on the cap and is measured by a gauge downstream from the cartridge.

Advantages

• One filter serves multiple respirators
• CPF-20 is easily converted to CPF-80 to service additional respirators
• Polypropelene filter cartridge casing eliminates corrosion hazard
• Filter cartridge lasts up to 3 months.
• Filters can be floor or wall mounted.
• Approvals and Certifications
• CPF filters comply with OSHA regulation 1910.94 (6) as a component of a total respirator system. To comply with OSHA regulation 1910.134 (d), the system must also include a NIOSH-approved, type CE, supplied-air respirator and carbon monoxide (CO) monitoring and/or removal system.

The Clemco light-duty blast suit protects the operator from the impact of rebounding abrasive. The suit is a cost-effective alternative to a heavy-duty suit for intermittent or short-term blasting, and for non-blast personnel working at the blast site. It weighs less than Clemco’s heavy-duty blast suit. The nylon and cotton construction is easily machine washable. Discarding the light-duty suit after a toxic dust job wastes less money. For rental outlets, the low-cost suit makes it possible to stock suits in sizes to fit almost any customer. (Optional gauntlet gloves protect hands and wrists.)

Advantages

• Weighs less and costs less than Clemco’s heavy-duty blast suit.
• Nylon and cotton construction is easily machine washable.
• Discarding the light-duty suit after a toxic dust job wastes less money.
