Powermatic manual Powermatic PM1900 Dust Collector, Filtering Efficiency

The POWERMATIC DC1900 is essentially the same machine but can be equipped with the fabric style bags (left) or the canister kit. (right) The difference in height between the bag and canister setups can be important in some shop environments with low ceilings or other height restrictions.

POWERMATIC PM1900 Dust Collector

The POWERMATIC PM1900 is designed with the power to work with planers, wide belt sanders and most woodworking machines. Its powerful dust-evacuating suction, effective filtering, multiple connection and large collection capacity make the POWERMATIC PM1900 a capable central dust collection system for the whole shop. Plus, it packs those capabilities into a durable, space-saving package that accommodates virtually any shop size and needs.

The POWERMATIC PM1900 is shipped as a bare

machine without filter elements or catch bags allowing the buyer to “design” the system they want. The fabric filter and catch bag sets as well as the pleated canister filters with five plastic catch bags are sold as individual kits. This allows the purchaser to save money by getting the POWERMATIC PM1900 with the filter style wanted without paying for and then discarding an unused “standard” filter and bag sets.

Filtering Efficiency

The bag filter elements are 20” in diameter and 48” in length. Upright hooks are included to support the bags when the POWERMATIC PM1900 is not running. Spring steel band clamps secure the filter bags to the twin collector housings. The fabric collector bags use spring retaining rings sewn into their upper edges that fit into a groove in the collector housings making installation and removal tool free. Many manufacturers use an outside band for securing collection bags that can be very difficult to work with, especially when done alone.

The bag type elements filters out 96% of 30 micron particles.

The canister filters are 20” in diameter and 29” long. The canisters mount directly to the collector housings and seal with factory installed foam gaskets within the canister flanges. Four finger- operated knobs lock each canister to the collector housings. Despite the canisters compact overall size, its pleated filter element has six times the filtering surface area of the fabric bag type.
