Nilfisk CFM has launched two NEW single-phase vacuums. The S2 and S3 industrial vacuum cleaners feature the Longopac® collection system, an “endless” bag that can be dispensed as needed to the desired length. Once filled, it can be cut, sealed, disposed and restored for a new use. LED indicators automatically monitor filter performance. Nilfisk CFM, www.NewNilfiskVacuums.com, (800) 645-3475.
