Mermade 36" x 60" Edge Outlet (BIF Replacement), Leaf Only

The Mer-Made 36" × 60" Edge Outlet (BIF Replacement) — Leaf Only (also cataloged as the Bare Leaf, Skeleton, or Core Assembly) consists of the fully assembled rigid thermoplastic structural frame, internal high-flow drainage grid, and welded side-discharge hub, excluding the fabric filter bag (cover) and sealing collar/gasket.

This configuration is engineered for municipal, institutional, and waterpark vacuum DE pits utilizing legacy BIF (Builders Iron Foundry / B-I-F Industries) side-header manifolds. It is specified when existing filter jackets are being reused or installed from bulk inventory, or when replacing damaged, warped, or cracked PVC frames in the filter bank.

Technical Specifications & Scope of Delivery

• Internal open-matrix polypropylene or ABS high-flow drainage grid core

• Heavy-gauge injection-molded edge discharge hub with integral stop shoulder | | Excluded Components | • Fabric filter bag / cloth jacket (Part # 775-COVER / VFC-3660-EO)

• Top closure clamp / laces / Velcro seam

• Edge sealing collar or compression gasket |

Structural Design & Internal Core

• High-Flow Drainage Matrix: Heavy-gauge, open-structure polypropylene or ABS drainage core designed to withstand high negative vacuum draw (up to 15" Hg) without deflecting inward or pinching the flow channels, ensuring fluid travels unrestricted across the entire 36" width toward the edge port.

• Perimeter Framing: Rigid extruded PVC/CPVC border framing with thermo-welded corner gussets. The vertical side member carrying the outlet hub is reinforced with internal gusseting to resist lateral cantilever torque and bending moments exerted by the side manifold connection during pump cycling.

• Molded Edge Discharge Hub: Permanently solvent- or hot-gas-welded into the vertical rail. Features an integrated stop shoulder to set the insertion depth into the BIF manifold receiver and prevent over-compression or damage to the sealing gasket.

Physical Dimensions & Weight Estimates

• Individual Bare Leaf Net Weight: Approximately 19.5 to 23.0 lbs (8.8 to 10.4 kg).

• Single Boxed Leaf Shipping Weight: Approximately 28 to 34 lbs (12.7 to 15.4 kg) in heavy-duty oversized corrugated cartons with edge guards.

• Master Pallet Lot (10 to 15 Bare Frames): Approximately 320 to 520 lbs (145 to 236 kg) freight-strapped to an oversized 42" × 66" wooden pallet.

Field Clothing & Installation Steps

1. Verify Handing & Elevation: Confirm the outlet spud matches the exact height and left/right orientation of your BIF vacuum header receiver before fitting the cover.

2. Inspect Frame Surface: Check the outer channel edges and bare grid faces for sharp burrs, rough weld beads, or cracks that could snag or puncture a replacement fabric jacket.

3. Fit the Replacement Bag: Slide the open-ended jacket over the frame, aligning the pre-cut, reinforced edge opening around the protruding side outlet spud.

4. Tension the Fabric: Pull the bag taut across the entire 36" × 60" surface to prevent loose fabric or wrinkling, then secure the top closure mechanism (Velcro flap, clamp bar, or laces).

5. Mount Gasket & Seat: Slide a new compression gasket or felt collar over the edge spud against the locating shoulder. Insert the spud horizontally into the BIF wall manifold socket, lower the frame onto the floor guide saddles, and tighten the upper hold-down rail.
