Silvent 220 F Adjustable Flexblow Hoses

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.

Replace open pipe of diameters:
4 – 6 mm
1/8” – 1/4”

SILVENT 220 F – 280 F: nozzle mounted on a bendable Flexblow hose. Keeps desired position, even at high pressure. Available in 6 different standard lengths. The Flexblow hose has a 1/4″ male connection thread. Same performance as 920 A


  • Reduces the noise level: 14 – 23 dB(A)
