Dust cups help keep your tablet press clean by blocking powder from entering the punch guides, cams, and die table. They’re simple to install and make a big impact on tooling life, product cleanliness, and overall machine performance. Made from durable, FDA-compliant materials, LFA’s dust cups are a practical solution for improving efficiency and reducing downtime. If you’re dealing with frequent cleanup or abrasive powders, dust cups are an easy upgrade worth considering.
Dust cups are designed to prevent powder from leaking into the punch guides, cams, and die table. When granules build up in those areas, it leads to unnecessary wear, cleaning, and possible tablet defects. Dust cups help create a clean seal around each punch head to keep contaminants out of critical areas.
By using dust cups on your press, you can reduce routine maintenance and protect your tooling investment.
Key Features of Dust Cups:
Made from FDA-compliant, pharmaceutical-grade materials
Available for B tooling, D tooling, and 1-1/4" punch sizes
Easy to install and remove—no special tools required
Multiple color options available to help with punch organization or line identification
Compatible with rotary tablet presses
Dust cups are most effective when used alongside upper punch seals to create a stronger barrier between your product and the mechanical parts of the machine.
If you're seeing powder buildup under the turret or frequent residue around the punches, dust cups can help fix that.
