Stabilize high-volume extractors with the P778311 replacement dust filtration element. 235 sq.ft area & 1.187" bolted base. Request a B2B quote today!


Maximizing extraction capacity within existing baghouse footprints requires extended, structurally stable components. The interchangeable replacement for the P778311 Dust Filtration Element delivers an upgraded 27.5-inch vertical span, packing an impressive 235.48 sq.ft of media. Engineered with a 1.187-inch Open-Closed Bottom (OCB) bolt hole, it guarantees immovable anchoring against violent reverse-jet pulses. Protect your exhaust blowers and ensure consistent, leak-free industrial air separation with this heavy-duty component.
Extended 27.5" Filtration Matrix: Increases the effective dirt-holding zone vertically. This allows the industrial replacement Dust Filtration Element to handle heavier particulate burdens seamlessly, delaying the onset of differential pressure spikes.
1.187" OCB Vibration-Proof Anchoring: The solid bottom pan features a pre-drilled bolt hole, allowing the cartridge to be securely clamped to a central tie-rod, completely neutralizing mechanical rattling during operations.
8.375" Updraft Exhaust Tunnel: The generous inner diameter guarantees an unrestricted pathway for cleaned air, mitigating aerodynamic friction and preventing choke-flow phenomena in heavy extraction networks.

Accountability drives Ayater's B2B manufacturing philosophy. Prior to global shipment, every replacement Dust Filtration Element passes targeted geometric audits, focusing specifically on the 1.187" bolt hole tolerance and pleat spacing integrity under ISO-compliant testing frameworks. We empower global maintenance teams with structurally infallible air separation assets.

A prominent metallurgy facility faced severe environmental compliance warnings. The intense vibration from their sintering exhaust fans was rattling traditional friction-fit filters out of their mounting holes, leading to massive raw dust bypass. By transitioning to the Ayater P778311 interchangeable Dust Filtration Element, the maintenance crew utilized the 1.187" OCB design to securely bolt the cartridges down. This mechanical upgrade completely eradicated filter dropping, reducing particulate emissions to compliant levels and saving 30% in monthly consumable costs.
Vertical Elongation and Tie-Rod Mechanics
In heavy-duty extraction engineering, increasing the filter length (such as to 27.5 inches) is an effective strategy to amplify the "Air-to-Cloth" ratio without expanding the housing cabinet footprint. However, simply lengthening a cylinder introduces bending and vibration vulnerabilities. When reverse-pulse compressed air strikes the inner core, the bottom of an unsecured long filter will swing like a pendulum, eventually tearing the top seal.
The integration of the OCB (Open-Closed Bottom) with a 1.187-inch bolt hole neutralizes this aerodynamic risk. A heavy-duty steel tie-rod drops through the 8.375-inch internal core, allowing a nut to clamp the bottom pan firmly upward. This converts the long 27.5-inch filter into a rigid pillar. The pneumatic cleaning energy is forced to expand outward radially, snapping the 235.48 sq.ft of pleats evenly and discharging the dust cake without compromising the mechanical seal.


Ayater stands as a highly digitized industrial manufacturing base exclusively dedicated to B2B air and fluid separation technologies. By combining automated pleating systems capable of handling extended 27.5-inch profiles with heavy-duty CNC metal stamping, we construct formidable filtration consumables. Our strategic vision is to bypass supply-chain friction, equipping global industrial operations with direct-sourced, compliant extraction components.
