Silvent 220 F Adjustable Flexblow Hoses

SILVENT 640 being used for cooling and cleaning

Flexblow hose keeping a crosscut saw clean

SILVENT’s FLEXBLOW hose is a bendable hose that keeps the desired position, even when blowing at high pressure. Since the hose can be bent to the optimal blowing angle, both noise level and air consumption can be kept to a minimum.

New technology has provided the system with increased durability and improved bending and blowing characteristics. The hose is oil resistant and can also be used with coolants. SILVENT’s flexblow hoses are available in 6 different standard lengths, with either 1/8” or 1/4” connection. SILVENT’s 5001, 208, or 920 nozzles can be combined with the flexblow hoses. Flexblow hoses fitted with SILVENT nozzles fully meet OSHA safety requirements. Patented.
