Clemco Big Clem multi-outlet, bulk abrasive blast machines are rugged, reliable, and efficient. Designed for large jobs, where multiple blast operators are needed, the Big Clem offers the convenience of a large supply of abrasive, loaded at one time, ensuring more blast on time, and saving the time and labor of refilling smaller machines.

Big Clems are available in three standard sizes: 60, 120, and 160 cubic feet abrasive capacity and, depending upon the model, for up to four blast operators. Units are rated 150 psi working pressure. Each model is available as stationary, yard towable, or highway towable to suit the application.

Each operator station is fitted with Auto-Quantum (pneumatic or electric) pressure-hold remote controls, which allow each operator to start and stop independent of the others. The Quantum is an all-media valve, making it possible to switch between expendable mineral or slag abrasives to steel grit as necessary. Pneumatic remote controls are best when the blast hose is 100 feet or shorter; beyond 100 feet electric remotes are recommended to minimize the response time at the nozzle for beginning or stopping blasting.

Standard Features

Standard Features

 N/A
  • 150 psi working pressure.
  • 2 outlets, pneumatic pressure-hold remote controls.
  • Fail-to-safe, normally-closed, all-media Auto-Quantum abrasive metering valve that is easy to operate and requires little maintenance.
  • Flexible pusher lines simplify valve maintenance.
  • Media shut-off valves allow servicing individual metering valves leaving others operational. Generous clearance below vessel for valve maintenance.
  • Automatic pop-up filling valve, with debris screen, and swing-open rain cap—the safest option on the market—eliminates the potential for injury possible on units with camlock closures.
  • Large 12-inch x 16-inch man-way permits access to pressure vessel chamber for maintenance service.
  • One ladder allows easy access to pop-up valve for machine filling
  • One hose support bracket for storing blast hose.
  • Heavy-duty lifting eyes mounted on the vessel.
  • Abrasive cut-off feature on the remote controls allow work surface blow-off.
  • Large, built-in 1600 CFM moisture separator/manifold helps to reduce moisture, a naturally-occurring by-product of compressed air. Supports up to four No. 8 nozzles.

Features

Options

 N/A
  • Electric remote option includes weather-proof control panel and anti-freeze injector capability.
  • Stationary models for fixed installation are ideal for industrial applications.
  • Yard-towable models offer increased flexibility for moving the unit on site; and highway-towable models are the most versatile offering the convenience of towing the machine to the job site.
  • Optional 160 cuft 8-ton off-shore model with full-load lifting eyes and integral base for super-sack frame.

Auto-Quantum Metering Valve

 N/A
  • Unrestricted abrasive flow through metering valve.
  • Metering takes place upstream—not at the plunger—eliminating direct exposure to media. Does not require urethane or tungsten inserts.
  • Normally-closed design requires compressed air to open.
  • 45-degree abrasive feed assures constant, uniform abrasive flow.

Big Clems are Safe, Reliable and Efficient

 N/A
  • Automatic pop-up valve eases refill and cannot be opened while machine is under pressure.
  • 2:1 semi-elliptical head provides more abrasive storage for maximum abrasive capacity.
  • Integral moisture separator and air manifold designed to eliminate restrictions that cause air-flow loss, while providing equal, moisture-free air to each operator.

Durable Transport System

 N/A
  • Big Clems torsion spring suspension provides strength beyond load capacity.
  • Towable models feature rugged trailer assembly for negotiating rough terrain. Wheels and tires rated for easily handling load at highway speed.
  • Highway models equipped with four-wheel electric brakes, emergency breakaway switch, and high-visibility tail lights, brake lights, and turn signals.
