Dental Air Polisher Sandblasting Machine 2 Hole / 4 Hole Air Prophy Unit

The Dental Air Polisher Sandblasting Machine is an air-driven benchtop prophy unit that mixes compressed air, water and prophylaxis powder into a controlled spray to remove extrinsic stains, plaque and soft deposits from tooth surfaces.

It connects to a dental chair through a standard 2-hole (Borden/B2) or 4-hole (Midwest/M4) handpiece tube, holds up to 42 g of powder per fill and delivers 1.5–3.8 g/min of powder at a rated water spray of 235 ml/min.

Key Benefits of This Air Prophy Sandblasting Unit

• Fast stain and plaque removal the air, water and powder jet lifts tobacco, tea and coffee stains, tartar-related discolouration and plaque biofilm while being gentle on gingival tissue.
• Dry, clog-resistant powder flow an integrated air filtration unit (filter cup) stops moisture and oil from the air line reaching the powder, preventing caking in the handpiece and hose.
• Separate air and water channels the air tube and water tube run independently, so air and water never mix inside the line.
• Simple chairside installation plugs into an existing 2-hole or 4-hole handpiece tube and runs on the dental unit’s compressed air supply.
• Compact and lightweight small metal housing with a single main switch suits clinics with limited bench space.
• Easy hygiene the handpiece tip detaches for cleaning and the kit includes cleaning brushes and a cleaning needle.

Features and Controls

Large-Capacity Powder Tank

The top-loading powder tank with a sealed screw-on lid holds up to 42 g of prophylaxis powder per fill, enough for multiple patients between refills.

Independent Air, Water and Powder Adjustment

Rear-panel brass knobs adjust the air valve, water volume and powder amount, so the clinician can balance cleaning power against patient comfort for each case.

Drain (Desander) Button

Press the drain button three times before each use to purge condensed moisture from the filter cup and keep the powder dry.

Sandblasting On/Off Switch

A front-mounted toggle switch controls the powder (sandblasting) function, while the handpiece is activated from the dental chair foot control.

Detachable Prophy Handpiece Tip

The angled nozzle unscrews from the handpiece for one-click cleaning of residual powder, and the handpiece works by pressing gently against the tooth surface at the correct angle.

Frequently Asked Questions

What is a dental air polisher?

A dental air polisher is a prophy device that propels a mixture of compressed air, water and fine powder onto the teeth to remove stains, plaque and biofilm faster than rubber-cup polishing.

Which variant fits my dental chair, 2-hole or 4-hole?

Count the holes on your chair’s handpiece tube. Two holes means a Borden (B2) connection choose 2-Hole. Four holes means a Midwest (M4) connection – choose 4-Hole.

What air and water pressure does it need?

The unit operates at 0.25–0.5 MPa air pressure and 0.2–0.5 MPa water pressure, which is within the normal range of a dental chair supply.

How much powder does the tank hold?

The powder tank holds a maximum of 42 g per fill, with a rated powder output of 1.5–3.8 g/min.

Which powder should I use?

Use a fine, dry prophylaxis powder made for air polishing devices, such as sodium bicarbonate or glycine-based prophy powder, following the powder manufacturer’s indications.

Does it need an electrical connection?

No separate power supply is required the machine is air-driven and runs on the dental unit’s compressed air and water lines.

Why should I press the drain button before use?

Pressing the drain button three times releases moisture collected in the filter cup, which keeps the powder dry and prevents clogging in the hose and handpiece.

Is the handpiece tip removable?

Yes. The tip unscrews from the handpiece for cleaning, and a cleaning needle and brushes are supplied in the box.

Is this air polisher certified?

Yes, it carries CE certification. It is intended for use by qualified dental professionals.
