Darlly High Flow ltration system are styled on the design of corrosion resistant FRP pressure vessels. These provide considerable reduction in capital investment versus stainless steel construction and make use of a quick-acting closure. Each vessel has the convenience of one lter element that can be exchanged in seconds.

High Flow lter elements are available in both polypropylene and glass micro-ber media in ratings of 0.5 to 100 microns, and in both nominal and absolute retention performance. The unique layered construction provides excellent retention across a wide range of ow rates. Each six inch diameter 60” length cartridge can handle ow rates of up to 500gpm with the inside-to-outside ow path allowing for high contaminant holding capacity. Superior ow and long lter life make Darlly HighFlow lters an ideal choice for a wide variety of critical process ltration applications.

The innovation of advanced German pleating technology allows the lter elements to offer higher surface area resulting in superior ow and media utilization. With a tapered pore structure and ne ber denier, the result is better dirt holding capacity, low resistance to ow, superior lter performance and overall better value for the user.

The inside-to-outside ow conguration and core-less construction of the Darlly HighFlow lter element allows it to be tightly compacted to minimize disposal costs. Maintenance requirements and production downtime is dramatically reduced in comparison with conventional depth lters. Service personal will nd it easy & convenient remove used elements since all solid contamination is trapped inside of the lter cavity.

Features(HIGH FLOW FILTER CARTRIDGES)


High Flow Capacity per Cartridge (vs. Conventional 2.5” Diameter Cartridges)	Less cartridges are required, therefore: Reduced cartridge handling time, storage space, inventory value, & disposal costs Reduced filter change-out time Fewer cartridge sealing points, reduced chance of fluid bypass
Advanced Pleat Design using Darlly High Grade Microfiber Polypropylene Media	High Dirt Holding capacity Superior chemical compatibility
Compact Design	Smaller housing envelope minimizes capital expense requirements Reduces system footprint
Easy to Operate	Minimum removal tools are required for filter change-out Push-to-Seat cartridge sealing mechanism provides positive seal Easy to install design handle facilitates cartridge installation and removal
Safe Materials of Construction Compliant with US FDA CFR-21 Requirements	Compatible in applications requiring direct food contact in food, beverage, & potable water processing

Features(HIGH FLOW FILTER HOUSINGS)


FRP - GRP housings	Superior chemical compatibility Can withstａnd higher pressures Ideal solution for highly saline water Lower weight of individual housings allow ease of handling
HighFlow Housing Capability versus Conventional Filter Housings	Saves time during routine servicing Filter sealing risks can be avoided Less individual cartridge seal points, reduces chance of fluid bypass No awkward davit arm or pulley mechanism to deal with to open the unit
IMP- Replacements & Damages	Smaller housing minimizes capital expense requirements Reduces system footprint
Ease of Use versus conventional Cartridge Filter Housings	No davit arm or tie rod issues to deal with. Easy to set-up by-pass flow connections.
Capacity Scaling	Additional housings can be added in parallel to scale-up or scale-down the system flow rate. No need to replace the mounting skid.
Reducing capacity	Remove Victaulic clamps and put the blind
Flexible Design Porting	Ports can be oriented at the installer's preferred orientation for maximum flexibility.
Victaulic grooved ends	Easy to connect and disconnect with our standard Victaulic style grooved ends
Corrosion-Free Construction	Totally corrosion-free system, so critically important in cases of highly saline SWRO plants
