Clemco 6 Cu. Ft. Contractor Machine with HP Respirator

Description

Strip heavy industrial rust using the Clemco 21549 Contractor Blast Machine to prepare structural steel surfaces for protective paint coatings. The ASME-coded pressure vessel holds 6 cu ft of abrasive media, paired with an Apollo 600 high-pressure respirator. Continuous high-volume grit delivery requires minimum 250 CFM air compressors, preventing operation with standard small shop air units.

Fabricated from heavy ASME-certified steel plate, the 24in diameter pressure vessel features an inverted top head and concave bottom. Base dimensions measure 31in wide by 42in deep with an overall height of 59in, bringing bare dry weight to 455 lbs. The pneumatic piping circuit uses 1-1/4in plumbing with a Quantum abrasive metering valve rated for 150 PSI maximum operating pressure.

Key Features of Clemco 21549

Commercial bridge painters and shipyard sandblasting contractors buy Clemco 21549 systems to maintain continuous surface profile cleaning. Purchasing managers select this contractor package to eliminate separate respirator sourcing while securing high-production grit metering.

• Pressure vessel holds 6 cu ft of blast grit to sustain 45 minutes of continuous high-production blasting.
• Quantum abrasive metering valve allows precise grit metering to reduce abrasive waste during heavy steel cleaning.
• Apollo 600 high-pressure respirator system delivers filtered breathing air to protect operators from toxic silica dust.
• Pneumatic Millennium remote controls allow instant pot pressurization and depressurization at the nozzle handle.
• Large 10in inspection handhole allows internal tank inspections to verify ASME shell thickness compliance.
• Heavy-duty 1-1/4in piping delivers unrestricted airflow to feed size 5 through size 8 venturi blast nozzles.
• Rugged tubular steel transport cart features wide pneumatic tires to roll across rough jobsite sand and gravel.
• Moisture separator removes liquid water droplets from incoming compressor air to stop abrasive clumping.

Pressure Vessel Pneumatic Flow Verification

Hydrostatic testing certifies the ASME pressure tank to 225 PSI proof pressure with zero weld seam deformation. Pneumatic metering tests confirm steady flow through a number 6 venturi nozzle at 100 PSI, requiring 220 CFM clean air. Pressure drop across the Quantum valve holds below 4 PSI during continuous grit injection. Acoustic sound testing registers 94 dB at 10ft during blast operations.

Industrial Blasting Usability Negative Filter

Do not connect this industrial blast pot to air supplies under 175 CFM or use unapproved breathing air compressors lacking carbon monoxide monitors. Operators wearing the Apollo respirator helmet and blast gloves maintain full trigger control using the pneumatic deadman safety lever switch.

• Drain accumulated water from the inlet moisture separator filter every 2 operating hours.
• Inspect the pop-up valve O-ring seal for grit erosion and air leaks every 40 hours.
• Check blast hose wall thickness and nozzle liner wear every 20 hours of production blasting.

Factory Warranty Terms Crate Package Inclusions

Clemco covers this contractor machine with a 1-Year commercial warranty against manufacturing defects and vessel failures. The factory wooden shipping crate contains the 21549 blast pot, Apollo 600 HP respirator, 50ft blast hose, remote control handle, moisture separator, and technical manual.
