Name: Bafter I Skimmer
Brand: Bafter

The Bafter I floats on the basin surface and drains the cleanest water from the top of the pool. A PVC arm with upper and lower flexible hoses connects the skimmer to the outlet structure, so the inlet rides up and down with the water level. An orifice sized for the basin sets the dewatering rate.

Anti-siphon tube and trash guard
Upper flexible hose with turnbuckles; rotate the hose during assembly to match its natural arc
Set over a depression with a stone ring to keep the skimmer off the bottom
Multiple units can serve one basin, each with its own connection to the outlet structure

Copy into your plan notes or project specifications, then fill in the skimmer and orifice sizes.

Surface skimmer shall be a Bafter Skimmer Model I, ___-inch, with a ___-inch orifice, as manufactured by Bafter, LLC, Tigerville, SC. The skimmer shall dewater the basin from the water surface through a PVC arm and upper and lower flexible hoses connected to the outlet structure, and shall include an anti-siphon tube and trash guard. Maximum pond water depth is 7 ft to overflow for the 10-year storm with the arm supplied. Set the skimmer over a depression with a stone ring to keep it off the bottom. Where a second skimmer is required, each unit shall have its own connection to the outlet structure. Inspect skimmers weekly as part of the required CEPSCI inspection.
