The Chicago Pneumatic CP 0004 is a pneumatic backfill tamper the pogo-stick compactor that packs trench backfill, pole bases and footing soils in lifts a plate compactor can’t reach. A 2-1/4 in. bore driving a long 6 in. stroke turns 28 CFM at 90 psi into 780 slow, powerful blows per minute through a 6-1/4 in. butt, with 42 lb of tool weight behind every strike.
At 50 in. overall with a 1/2 NPT inlet, it runs from a modest compressor on a standard contractors air hose, while heat-treated cylinders and chrome-plated pistons carry the service life; optional mufflers are available. The CP 0003 (18 CFM) and CP 0035 (39 CFM) bracket it on air demand among our backfill tampers, and the tampers buyers guide covers sizing a tamper to the job.

CP 0004 FAQ
What size compressor does a backfill tamper need?
The CP 0004 draws just 28 CFM at 90 psi through a 1/2 NPT inlet, so a modest contractor compressor runs it all day.
What else is the CP 0004 used for besides tamping backfill?
Chicago Pneumatic also rates it for cleaning and roughing concrete and construction joints, and for producing ornamental or contrasting finishes on building structures.
CP 0003, CP 0004 or CP 0035 which one?
The three tampers bracket on air demand 18, 28 and 39 CFM so match the tamper to your compressor and how much compaction the fill needs; the rest of the line lives on the Chicago Pneumatic backfill tamper page.
Can it run quieter?
Yes optional mufflers are available for quieter operation, and the heat-treated cylinder and chrome-plated piston are unaffected either way.
