Air Techniques International Adds High Flow Option to 100X Automated Filter Tester EN 13274-7:2019 Paraffin Test

The new high flow option allows greater flexibility in applications and can increase production throughput while meeting particle size and concentration specifications.

OWINGS MILLS, MD — 21 July 2021 — Air Techniques International (ATI), a global leader in the design and manufacture of specialized testing equipment for HEPA filters, media, filter cartridges, respirators, and protective masks, announced today the addition of the High Flow EN 13274-7:2019 compliant Paraffin Oil option to its 100X Automated Filter Tester lineup. The new High Flow option provides greater flexibility for testing a wider range of masks and cartridges, including PAPR cartridges, and increases production throughput vs. standard flow options.

“The High Flow option is a valuable feature for manufacturers looking to increase production rates while still complying with the strict standards for particle size and concentration specified in the EN 13274-7:2019 Paraffin Test,” said Gautam Patel, Global Product Manager. By offering a flow rate of 170 L/min vs. the standard rate of 120 L/min manufacturers can benefit from increased production throughput by testing multiple filter cartridges at once.

The High Flow option also allows testing of a wider range of applications. “A common application that requires a higher aerosol challenge flow rate is the testing of PAPR (Powered Air Purifying Respirator) filter cartridges. PAPRs typically require flow rates much higher than standard filter cartridges,” said Patel. The High Flow option is ideal for EN 12941 and EN 12942 PAPR testing standards.

The High Flow option allows more cartridges to be tested at once vs. standard flow rate units. This is important to manufacturers using the 100X in their high-capacity automated production lines. Complete test cycles can be performed in as little as six seconds.

To order the High Flow option, simply specify it at the time of order. Standard lead times apply, which currently are an industry low of 8-10 weeks.

In addition to EN 13274-7:2019, the 100X Automated Filter Tester product range meets other major industry standards, such as NIOSH 42 CFR Part 84, GB 2626, ISO 23328, JICOSH/JMOL, ASTM F3502-21, and more. The 100X Automated Filter Tester is used worldwide in production, quality control, and R&D applications to test and validate filter media, cartridges, and respirators.
