The Aqua-Flow System® Features micro-tubular brush bristles attached to a durable polymeric holder and provides continuous water to your grinder head. The system not only provides continuous water to your grinder head, but also cleans simultaneously at a surprisingly affordable price. The Aqua-Flow System® is available as a complete system with replacement brushes sold separately. The Aqua Flow System® - Proprietary brush bristles transfer water from the reservoir to the grinder bit continuously,. - Anti-Clog Technology Aqua Flow System’s® anti-clog technology allows water to flow continuously, drawing sludge away from the grinding bit. Conventional sponges cause clogging, making it necessary to continuously clean the sponge. Prevents Dry-Out- With conventional sponges water needs to be added every 10-15 minutes after grinding is commenced due to dry-out. With the Aqua Flow System™, the brush bristles do not absorb sludge or dry-out. - Prolongs Bit Life The life of your diamond-grinding bit will be prolonged; this is because the proprietary brush bristles constantly clean the grinder bit while supplying water continuously. Self-Locking Snap-In Holder An equally important advantage of Aqua Flow System™ is its self-locking snap-in holder. Once the system is inserted, it will not detach as conventional sponges do. - MODELS: AFS-A For use on Glastar's G-8 All Star. AFS-DS For use on Glastar's G-14 Diamond Star and G-12 Super Star.
