EMS AIRFLOW Prophylaxis Master: combined scaler and air polisher
Last updated: October 16, 2026. Independent reference. Preventio Hub has not bench-tested this unit.
Summary
The AIRFLOW Prophylaxis Master (EMS product code FT-229) is a combined tabletop unit from EMS for its Guided Biofilm Therapy (GBT) protocol: AIRFLOW (supragingival air polishing), PERIOFLOW (subgingival air polishing) and PIEZON (piezoelectric scaling, "NO PAIN" technology) from one control unit with a touch panel and a wireless pedal. EMS presents the GBT Machine (K253254) as its successor, so ask a supplier about availability, service and parts for both units.
Who it may suit
- Practices running EMS's GBT protocol that want one console for scaling and air polishing.
- Clinics that want an FDA-cleared erythritol powder (AIRFLOW PLUS, K171189) with the unit.
It may be less suited to buyers who want to source powders from several suppliers, who only need supragingival polishing (see handpiece vs combined unit), or who prefer EMS's newer GBT Machine.

Powders
FDA's summary lists AIR-FLOW CLASSIC (sodium bicarbonate), SOFT and PERIO (glycine) and PLUS (erythritol). AIRFLOW PLUS has its own clearance (K171189, September 11, 2017, class I; erythritol with 0.05% cetyl pyridinium chloride as preservative; EMS says CPC is used in the U.S. and Canada). Ask the supplier whether other powders affect the warranty.
Installation and reprocessing
Water 2-5 bar and dry air 4.5-7 bar are required (IFU). Heat-sterilize handpieces between patients and follow the validated EMS instructions (CDC: handpieces and attachments that can be removed from the air and water lines must be cleaned and heat sterilized between patients). For dental unit water quality, CDC recommends output water of 500 CFU/mL or less of heterotrophic bacteria for routine non-surgical treatment.
