Pleated Technology Advantage

Pleated media construction provides 5-15 times surface area versus equivalent size felt bags. Increased area enables higher flow rates per element. Fewer housings required for given capacity reducing system size and cost.

Housing Configuration

Vertical pressure vessel with quick-opening cover, single or multiple pleated bag positions, inlet directing flow to bag openings, outlet from filtered liquid, drain connection. Design accommodates pleated bag dimensions.

Pleated Bag Construction

Polypropylene, polyester, or nylon media pleated and formed into bag shape. Support cage prevents pleat collapse under pressure differential. Typical surface area 25-50 sq ft per bag versus 3-8 sq ft for felt bags.

Flow Capacity

Single high-flow pleated bag handles 50-100 GPM compared to 10-20 GPM for felt bags. Multi-bag housings provide exceptional capacity - 6-bag vessel processes 300-600 GPM in compact footprint.

Operating Pressure

Design pressure 150 psig standard with higher ratings available. Swing bolt or quick-opening covers enable rapid bag changes. Pressure rating per vessel size and application requirements.

Micron Ratings

Available 0.5-100 microns absolute or nominal. Fine ratings for polishing applications. Coarse ratings for pre-filtration. Absolute-rated media for critical particle removal. Rating selection based on contamination and product requirements.

Material Selection

Stainless steel 304/316 for corrosive, food, or pharmaceutical applications. Carbon steel with coating for water and mild chemicals. Housings compatible with pleated bag materials and process fluids.

Differential Pressure

Clean DP 3-8 psi depending on rating and flow. High surface area maintains lower DP versus felt bags. Replacement typically at 15-30 psi. DP monitoring optimizes bag life and system performance.

Applications

High-volume cooling water, process water polishing, chemical filtration, coating and ink filtration, beverage and food processing, wastewater treatment, and any high-flow application requiring compact filtration.

Installation Density

High flow per bag reduces number of housings required. Smaller footprint saves valuable plant space. Lower piping and valve costs. Easier maintenance access with fewer vessels.

Bag Replacement

Quick-opening cover provides access. Used pleated bags lift out by support cage. Install new bags ensuring proper cage seating. Close cover and resume operation. Rapid changeover minimizes downtime.

Dirt-Holding Capacity

Pleated construction provides higher solids capacity versus equivalent felt bags. Extended service life reduces bag consumption and labor. Cost per gallon filtered lower despite higher initial bag cost.

Performance Consistency

Pleated media maintains consistent filtration throughout bag life. Uniform pore structure provides reliable particle capture. Minimal media migration ensures product quality.

System Economics

Higher capital cost per bag offset by superior flow capacity and longer life. Total cost of ownership lower through reduced housing count, piping, and maintenance labor. Typical payback 1-3 years for high-volume applications.

Performance Benefits

Exceptional flow capacity in compact footprint. Lower operating costs per gallon filtered. Reduced system complexity with fewer vessels. Proven high-flow technology for industrial filtration.

Construction Standards

Pressure vessels per ASME Section VIII. Materials compatible with process fluids and pleated media. Quick-opening closures per safety standards. Complete documentation with flow capacity specifications.
