RAY FOSTER Model AG03-MDCC — Alloy Grinder + Cyclone Dust Collector System (110V)
Complete dual-speed grinding station: AG03 Grinder + CDC1 Cyclone, factory-bundled at a better combined price
For over 85 years, RAY FOSTER Dental Equipment has manufactured precision Alloy Grinders in Huntington Beach, California for dental laboratories worldwide. The FOSTER Alloy Grinder is the proven workhorse for sprue separation and the finishing and polishing of chrome-cobalt Alloy framework — rugged, comfortable, and built to last.
The AG03-MDCC is the complete grinding station: the proven AG03 high-speed automatic-spindle Grinder paired with the RAY FOSTER CDC1 Cyclone Dust Collector. One catalog number, one purchase order — everything you need to set up a clean, efficient Alloy-grinding workstation out of the box.
Key Features
- Bundled CDC1 Cyclone Dust Collector — superior fine-particulate capture vs. bag-filter systems
- AG03 Grinder with dual belt-controlled speeds: 10,000 and 24,000 RPM
- Heavy-duty 1/4 HP capacitor-start Grinder motor in totally enclosed housing
- 1 HP CDC1 cyclone motor, 112 CFM suction, 59 dB noise level
- Precision high-speed automatic spindle
- Pre-wired auto on/off — cyclone runs only when Grinder runs
- UL-recognized and CSA-certified motors
- 110V 50/60 Hz (US domestic only — no 220V bundle available)
Key Selling Points
- Complete system — no separate dust-collector purchase needed
- Cyclone separation is the gold standard for fine Alloy dust capture
- Auto on/off saves filter life and reduces ambient noise
- Two-piece system installs in minutes — hose, plug, done
- Better total cost of ownership vs. buying AG03 + CDC1 separately
What Makes This Unique
Most lab managers eventually upgrade their basic Grinder to a cyclone-based extraction system — chrome-cobalt and titanium dust is hazardous to lungs and to equipment alike. The AG03-MDCC skips that two-step purchase. Buy once, install once, work clean from day one.
💡 Selling Tips for Sales Team
- OSHA / lab-health angle. Crystalline silica and metal dust from finishing operations is regulated. Cyclone-based extraction is the right answer for compliance-conscious labs.
- Math the bundle. Buying AG03 + CDC1 separately costs more than the AG03-MDCC bundle. Show the customer the line-item math.
- For high-volume CrCo labs. If they're grinding 10+ frameworks a day, cyclone capture pays for itself in filter changes alone.
- Position vs. AG04: AG04 has a built-in bag-filter collector. The MDCC's external CDC1 cyclone captures finer particulates and is the right answer for high-throughput labs.
- Position vs. AG05C: Same cyclone but with the variable-speed AG05 Grinder. If the lab works mixed materials, step them up.
