BHA® Preveil® ePTFE Membrane Laminated Filter Bags

High Efficiency Filtration For Dust Collector

BHA Preveil is made from PTFE resin, a substance with inherent non-stick properties that can be used to help your dust collector operate at maximum efficiency by providing:
• 99.99% efficiency
• Higher airflow
• Better cleaning
• Optimum emissions control

Media. Size. Construction. A lot of careful consideration goes into choosing the ideal filter for your dust collector. That’s where we come in. Our global team of industry specialists has decades of experience in the application of ePTFE membrane filter bags across a wide variety of industries. We’ll help you evaluate your options and select the right filtration solution that can help you improve operations and optimize baghouse performance. 

It’s not just the quality of the membranes we make that sets us apart—it’s what we do to them. Using our core competencies in membrane extrusion, lamination and finishing treatments, we design BHA Preveil membrane filter bags to improve filtration efficiency and operate at consistently low
differential pressures. This helps reduce filter changeouts and energy costs, extends filter service life, and can help lower particulate emissions across a wide range of applications.

Innovative Pleated Filter Elements Offering Proven High Performance And Durability

Whether used in new systems or serving as retrofits to existing dust collection equipment, these innovative pleated filter elements prove to be a versatile and cost-effective solution. 

Our pleated filter elements deliver valuable benefits:

• Provide superior filtration efficiency
• Promote better airflow for increased throughput
• Reduce air-to-cloth ratios
• Reduce operating differential pressure
• Reduce compressed air consumption
• Eliminate the need for cages
• Are easily installed and removed

Best of all, installation typically requires no modification to existing equipment. You can enjoy improved performance and energy savings without the expense of costly modifications.

Spunbond Media

The media is manufactured by the layering and calendering of fine denier fibers, it features a tight pore structure that better resists particulate penetration. Physically rigid, it can hold a pleat without the support of backing material and withstand temperatures up to 265° F (130° C). Spunbond media, when pleated and molded into the filter, can increase filtration surface area 3 to 4 times more than conventional filter bags. This can lead to a dramatic increase in filtration efficiency while operating at a significantly lower differential pressure.

Accurate Condition Monitoring made Quick, Simple and Cost Effective 

The icountOS (IOS) is an innovative solution to the challenge of measuring the quality of hydraulic oils and hydrocarbon fuels in many different applications: from renewable energy, marine and offshore, to manufacturing, mobile, agriculture, military and aerospace. 

How It Works

The IOS quality condition monitor for hydraulic oils and hydrocarbon fuels uses advanced technology to produce extremely repeatable results.
At the heart of the system is a sophisticated laser detector, using a light obscuration flow cell, providing continuous measurement of fluid flow passing through a sample tube.

Measurements are taken every second as standard, although measurement intervals and test period can be defined by the user, with results being reported immediately and updated in real time. Data is displayed on a built-in OLED digital display and can also be stored for subsequent upload via the embedded icount’s web page interface connecting through an RJ45 cable.

Features

Proven laser detecton technology

High onboard test data storage capacity

Quick connection
Tough storm case
Fast contamination detection
Complies with the latest standards
Long life remote operation
Fluid and pressure control
Pressure reducing valve (prv)

Most Up-To-Date Technology In Solid Particle Contamination Analysis

Parker Hannifn’s Icountpd Represents The Most Up-To-Date Technology In Solid Particle Contamination Analysis. The Icountpd Is A Compact, Permanently-Mounted Laser-Based Particle Detector Module That Provides A Cost-Effective Solution To fluid Management And Contamination Control.

The icountPD has just one setting to control the accuracy, stability and sensitivity of the measurements and that is the ‘Measurement Period’. This can be set from fve seconds to 180 seconds. The longer the Measurement Period, the more contaminant is measured, averaging out any spikes seen on a smaller sample. The shorter the Measurement Period the more sensitive the icountPD is to small slugs of contaminant, but also the performance on clean systems can be reduced. Thus, the user can select how sensitive the icountPD is to spikes of contaminant, and how quickly it responds to contamination levels above the set point (‘limits’)
