Miami, FL 33166, United States, 11th Nov 2026 – Pullner, a specialist manufacturer of filter cartridges and housings, has introduced capsule elements for industrial filtration buyers. According to the company, each capsule seals a pleated filter element inside a molded polypropylene body, so that the filter and its housing form a single disposable unit. Pullner lists the capsules for use in microelectronics, pharmaceutical, water and printing applications.
Pullner describes itself as a manufacturer rather than a trading company, with a 15,200 square meter ISO 9001 factory in Shanghai. The company states that the site has more than 30 production lines and produces more than 4,000 elements a day. Pullner also makes filter cartridges and housings (link pending) for customers in the United States and other markets, with locations in Miami, Florida, and Dubai.
How the Capsules Are Built
The company says its capsule shells are molded in house, and that the elements are thermally welded without adhesives. The capsules are produced in a cleanroom, Pullner says, and each element is integrity tested. The factory includes cleanrooms alongside its production lines, the company states.
“A capsule removes the housing from the changeout, so the choice of media and the connection type become the main decisions for the buyer,” said Lucy, Sales Manager at Pullner. “With the housing built into the unit, the question for a buyer becomes what the fluid requires, and each series comes with sizes and ratings that can be decided against. That keeps the selection practical for engineers and purchasing teams alike.”
Pullner lists four filter media for the capsules. Polypropylene and glass fiber are depth media, described as nominally rated, while PES and PTFE are membrane media, described as absolutely rated. The company describes PES as hydrophilic and low in protein binding, and notes that PTFE is hydrophobic and needs pre-wetting for liquids.
What Buyers Can Specify
Pullner offers three capsule series, with outer diameters from 72 millimeters to 250 millimeters. The company states that the N/S series is offered in five lengths and with NPT and Swage connections.
For that series, Pullner lists filtration ratings of 1 to 10 micron and a maximum differential pressure of 4.1 bar, or 60 PSI. The two larger series carry pressure ratings of their own and a maximum temperature of 80 degrees Celsius, according to the company.
The company names six application areas for the capsules. Beyond microelectronics, pharmaceutical, water and printing, they include laboratory and water sampling and new energy uses such as battery slurry and coating fluids.
Testing, Samples and Ordering
Pullner states that its in-house laboratory carries out particle counting, pressure drop and material compatibility testing. According to the company, the sealed format means that no cleaning validation is needed for the housing, fluid loss at changeout is lower and changeover is faster. The company presents these as the benefits of the sealed format, and adds that capsules can be sized to the batch.
The standard lead time for capsules is 10 working days, with a minimum order of 50 pieces, the company states. Pullner also offers sample testing and up to two samples. It does not claim a match with any other maker’s product until the match has been validated on the customer’s own process.
Looking Ahead
Pullner says it works with buyers on media selection, sample testing and custom filter design. The company states that custom capsule bodies, other sizes and adaptors require new tooling.
“The aim is to match a capsule to the fluid, the batch size and the connection that a customer already uses,” said Lucy. “Where a standard series does not fit, the conversation moves to a custom design and the tooling that goes with it. Starting from the customer’s own process keeps the outcome grounded in what the application needs.”
