Application guide
Polyurethane dry material handling hose
flexVAC™ U 140 ST is the grounded polyurethane dry-material option for 4- and 6-inch systems. It supports visual flow inspection, but its published vacuum limits are 21 inHg at 4 inches and 17 inHg at 6 inches.
Heavy-duty abrasion resistant suction and discharge hose
flexVAC™ 180 STAR combines abrasion-resistant SBR construction, static-dissipating carbon black and a copper grounding wire for demanding dry-material handling.
Medium-duty wet & dry material remote hose with grounding wire
flexVAC™ lite U Boom ST provides a polyurethane liner, static-dissipating construction and a copper grounding wire for abrasive recovery. It is the lighter boom-hose option and is not food grade.
Notes: Use the grounded material-handling progression for insulation removal. The selected diameter must meet the actual system vacuum.
Identify the recovered material, sharp debris, contaminants and temperature before use. Confirm the published pressure, vacuum, temperature and bend-radius limits for the selected diameter and complete assembly. Connect and test the hose grounding wire as part of the complete bonded and grounded system wherever required. Static-dissipating material alone does not provide a grounding-wire connection.
Distinction: flexVAC™ U 140 ST covers grounded recovery in 4- and 6-inch systems. flexVAC™ 180 STAR provides heavy-duty grounded rubber construction. flexVAC™ lite U Boom ST combines grounded polyurethane-lined construction with handling suited to demanding insulation removal.
Exclusion: An ungrounded substitute is outside this grounded removal selection. Static-dissipating material alone does not meet a hose-grounding-wire requirement.
