Pneumatic Pavement Breaker Demolition Hammer Sullair MPB90A 90lb Jack Hammer 114

Designed for Work Efficiency and a Long, Trouble-free Life

High-Wear Parts Reduced

The Sullair breakers have eliminated most high-wear parts. Fewer parts mean less wear, less maintenance, and less downtime.

No Tappet System

Unlike conventional breakers, Sullair breakers have no multi-part tappet system. With fewer parts, wear is reduced and risk of air leak is minimized. With no tappet system, which requires three independent impacts, noise is also reduced.

One Piece,
Non-Protrusive Housing

A leakproof air cushion forms at the end of the piston stroke and stops the piston from direct impact when the tool is not breaking. The elimination of side rods, nuts, and springs makes Sullair breakers sleeker and more comfortable to operate.

Minimal Lubrication Required

With only two parts moving during operation, normal oil carry-over from the compressor, combined with moisture in the air, will usually provide sufficient lubrication under normal operating conditions. Manual lubrication before storage is sufficient.

Direct Impact Piston

One moving impact part minimizes maintenance.

Parts Interchangeability

Standardization of design permits a high degree of interchangeability of parts between Sullair models.

Quieter

The piston, impacting directly on the steel shank rather than a tappet, reduces noise level of the breaker.

Smoother Operation

Reduced kickback is less fatiguing to the operator.

Improved Latch Design

Durable double roll pin permits easy steel changing.

Less Air Consumption

The direct impact piston design, non-corrosive distribution valve and one-piece housing dramatically reduce air consumption. You can operate more tools from a single compressor. For example, a 125 cfm compressor will operate two MPB 90 breakers.
