For Nutone central vacuum power units, synthetic sub micron disposable filter bags made from non-woven filter media. These cloth like filter bags provide superior airflow
performance and particle retention. The Synthetic filter bags are the same size as standard paper bags (Nutone # 391 & 44186) but provide much more debris holding capacity as suction and airflow will not be "choked off” by clogged paper pores allowing you to fill the bags much more then standard paper.
SYN391 synthetic disposable bags fit all bagged collection metal body (non VX series) power units excluding the CV-850. Pleated design measures 25.5" tall with a 2" intake opening and latex sealing gasket. The collar has a self-adhesive closure to seal the bag when full for hygienic disposal. Upgrade the cleaning power and the filtering performance of your central vacuum with a Synthetic Disposable Bag, the easiest and most effective central vacuum upgrade available.
Each package contains 3 replacement bags.
