Air hydraulic drilling unit
Air Hydraulic Drilling Unit BE(F)22
The basic design he BE(F)22 consists of a vane motor powered by compressed air, a pneumatic cylinder, and a closed hydraulic system. The total stroke length can be variably subdivided into rapid advance and working feed across the whole range. The throttle/check valve in the hydraulic system permits exact setting of the rate and high speed return.
• Extremely compact design
• Built-in hydraulics for controlled working feed
• Adjustment of drilling depth with positive stop guarantees a high degree of accuracy
• Low noise level
• Minimal air consumption
