Oztec's "High Efficiency RubberHead^TM" Outperforms any other type of vibrator

Epoxy coated rebar presents a particularly troublesome problem. Steel heads act like an electric hammer, striking any rebar or forms they contact, over 10,000 times per minute, with a force from hundreds to over 2,000 pounds per blow. Contact with a steel vibrator head of as little as one second can chip enough coating to subject the steel to deep rust. Oztec's patented High Efficiency "RubberHead^TM" vibrator head not only meets DOT non-metal head specifications for protecting coated rebar and expensive forms, but exhibit some very special and unique properties. The High Efficiency "RubberHead^TM" urethane dimpled construction sends strong shock waves off the entire length of the head, with a larger radius of action, producing denser concrete with less voids to patch.

Oztec's patented "High Efficiency RubberHead^TM":

• Will outperform any other type of vibrator?round, square, hi-cycle, etc?Any Type!

• Will protect epoxy coated rebar and expensive forms.
• Is outstanding in low slump (to "0" slump) concrete.
• Essential in large pours of very stiff concrete. 
• Makes concrete denser with less voids to patch.
• Vibrates @ 12,000vpm, never drops below 10,500vpm when lowered deep into low slump concrete.
• Provides Superior Action.
• Is an absolute must for Architectural concrete where cosmetic surfaces are essential.
• All Oztec vibrators meet or exceed ACI specification # 309

Why the Oztec "RubberHead^TM" outperforms any other type of Vibrator.
(a.) When a smooth vibrator head (round, square or any other shape) is lowered into a relatively stiff concrete batch, the front or nose of the vibrator drills a hole. It pushes away concrete faster than it can return. Result, shock waves produced mostly from the vibrator's front end.

(b.) Oztec's patented "RubberHead^TM" has a large number of openings which allow wet concrete to cool the inner shell. These openings act like "suction cups", which keeps concrete in contact with the entire length of the vibrator head, sending strong shock waves into the mass.

Prevent Hang-ups in Congested Rebar With Oztec extension pieces, you can greatly reduce the chance of vibrator heads getting caught in the rebar. Oztec RubberHeads? or Steel heads have the option of being equipped with extension pieces.
