Prior to 1990, all Sly dust collectors utilized an envelope style filter bag. Many long-time Sly customers are still operating our durable and reliable Dynaclones, Pactecons, and Shaker-cleaned dust collectors.
TubeJet collectors (pulse-cleaned styles with tubular style bags) surpassed the envelope style dust collectors due to their flexibility to handle many types of applications, ease of customization, ability to clean on-line on a 24/7 basis, and their lower operating pressure drop . As the Tube-Jet dust collector has become the new standard over the years, Sly has continued to support replacement part business for our legacy models. Sly’s aftermarket and engineering staff retain significant experience and knowledge about the vintage equipment.
While the legacy models are no longer marketed as new equipment, Sly can occasionally offer duplicate construction for those customers who have come to rely on these models and have circumstances requiring an “in-kind” replacement. Please contact us for more information.
Sly Legacy Models
The Dynaclone filter uses a continuous, gentle reverse air process to clean the bags via a heavy duty bag cleaning traveler in the clean air plenum. Type “A” Dynaclones have 3 tiers of bags and type “B” Dynaclones have 2 tiers of bags. While the cleaning process utilizes a reverse air process which takes a portion of the bags off line during cleaning, there is no interruption of operation as the cleaning arm travels back and forth. Common replacement parts for a Dynaclone include envelope filter bags, bag hardware including spacers, eyebolts, springs, front and back mullions; multi-seal and roll-clean traveler parts, gaskets, doors, blowers, fans, rotary valves, and screw conveyors.
Sly Pactecon collectors were designed for low headroom applications and offered side bag removal without entering the filter housing. Sly’s PC-100 Series offered one tier of filter bags and the PC-200 Series offered two tiers of filter bags. In either model, the filters are arranged in “cells”. The off-line cleaning system takes one cell at a time off line and cleans it with a lower pressure, higher volume of cleaning air than a typical on line cleaning pulse jet collector. PC-100-4 and PC-200-4 units contain 8 bags per cell and PC-100-6 and PC-200-6 units contain twelve bags per cell. Common replacement parts include envelope filter bags, bag hardware including spacers, eyebolts, springs, front and back mullions; diaphragm valve, solenoid valves, timer boards, gaskets, doors, blowers, fans, rotary valves, and screw conveyors.
Shaker-Cleaned Dust Collector
Sly’s envelope style shaker collectors were designed for applications where periodic off-line cleaning was practical. The dust would deposit on the outside surface of the bags and intermittent shaking would dislodge the dust when the system fan was shut down. A type 360 Shaker had three tiers of bags and a Type 260 Shaker had 2 tiers of bags. Common shaker replacement parts include envelope filter bags, bag hardware including spacers, eyebolts, springs, front and back mullions; shaker cleaning motors and parts, gaskets, doors, blowers, fans, rotary valves, and screw conveyors.
