Phase Converter for a Dust Collector

Phase Converter for a Dust Collector

Industrial dust collectors are essential for safe, code-compliant woodworking and manufacturing operations. Large central dust collection systems almost always use three-phase motors—they are more efficient, run cooler, and last longer than single-phase units of the same HP rating. A rotary phase converter is a common and reliable way to run them on single-phase service.

How to Size a Phase Converter for a Dust Collector

Dust collector motors have a moderate-to-heavy starting load because of the large impeller they spin up from rest. We use a 2.5× multiplier for accurate sizing:

For example, a 10 HP dust collector needs at least a GP25NL. A 5 HP unit needs a GP15NL (rounding up from 12.5). Sizing slightly generous here protects both the converter and the dust collector motor from heat stress during long startup cycles.

460V Dust Collectors

Many larger industrial dust collectors—particularly those rated 10 HP and above—are wired for 460V three-phase. If your dust collector is a 460V unit, you will need the NLT model, which includes a built-in step-up transformer to take your 230V single-phase service up to the 460V three-phase your machine requires.

Common Woodworking Shop Setups

It is common in woodworking shops to run a dust collector, a table saw, and a planer all from a single phase converter. If you have multiple machines, let us know all of the motors and HP ratings involved. In most cases, one properly sized Phoenix GP converter handles the whole shop.

Things to Check Before You Order

• Motor HP (on the motor nameplate)
• Operating voltage: 230V or 460V three-phase
• Available single-phase service amperage (to make sure the converter fits your service)

Phoenix GP series converters are built for continuous-duty operation, making them ideal for dust collectors that run all day. They are quiet, efficient, and backed by a 5-year warranty.
