Sierra Polymer's STAT-VAC line of Conductive Vacuum Hoses are engineered to directly replace conventional "strap-grounded" plastic hoses on Excellon and other multi-spindle drilling and routing machines.
STAT-V AC is a highly conductive ( 150 ohms per inch ) carbon coated elastomer. STAT-V AC 1.1 has a larger diameter 1.062" O.D. and provides a 60% flow volume increase.
The coating is uniformly applied to the outside surface of the hose. The hose ends of each length are dipped coated to insure I.D. to O.D. continuity. This procedure demands STAT-VAC and STAT-VACI.1 be sold exclusively in "kit" form.
•   Adaptability - STAT-V AC with an inlet hose size of .875 O.D. and .687" I.D. can be used with most multi spindle drilling and routing machines. The larger diameter STATVACI.I has a 1.062" O.D. Pressure foot adapters can be retrofited for use on most multi-spindle drilling and routing machines.

• Conductivity - STAT-V AC is a highly conductive colloidal carbon coated elastomeric tubing. With a volume resistivity of 150 ohms per inch, STAT-VAC hoses effectively dissipate static electrical charge caused by the removal of glassepoxy chips from the drill heads.

When using standard vacuum hose, high velocity air movement and particle abrasion on the inside walls of the vacuum hose generates static charge. Without an effective method of grounding static charge, • Reliability - STAT-VAC Vacuum Hoses are manufactured from materials which last up to fifteen times longer than original hoses.
the charge either dissipates through the drill bit resulting in damage to the board, or dissipates through the controller damaging sensitive boards. STAT-VAC eliminates problems associated with static electrical discharge.
STAT-VAC Conductive Vacuum Hose was developed by Sierra Polymer in cooperation with Excellon Automation Engineering and is original equipment on all Excellon Mark VII and later machines.
Original equipment hoses made of PVC typically last 800 hours, while STAT-VAC will last approximately 12,000 hours.
