What is Primpact 

THE PRIMPACT ENGINE:
THE HEART OF THE 250 / 550

Offers reliability, extended performance and
an unequaled smoothness of operation.

• Reduced wear effect and quick interchangeability of PRIMPACT engines between same generation units.
• High-speed action and few moving parts, for a powerful yet soft stroke, a shorter air-saving cycle and increased precision.
• Short nose and compact valve design provide an all-around striking surface and enable the nailing of more boards (4 1/2” closer) to the end walls.
• Finely threaded screw-in cartridge assembly for precision, easy on-site dismantling and durability.
