The Quad Pulse Package compact dust collector provides a cleanable filter system for the pharmaceutical and chemical industries.

Combining Performance with Economy

Many processes in the pharmaceutical industry can produce hazardous dusts in high concentrations. Cleanable filter systems are sometimes necessary to facilitate continuous manufacturing processes, preventing regular, expensive filter replacements.

The Quad Pulse Package PX utilizes segmented cleaning of the filter cartridge to provide the following benefits:

• Economical, space-saving cleaning unit requiring just a single primary filter cartridge.
• Cleaning during operation for production process and product quality control.
• Efficient segmented design allows cleaning with low pressure to further reduce noise and back pulsing
• Low pressure drop across the filter for energy cost savings.
• Camfil pleated filter technology provides exceptional dust release, enabling extended filter service life and reduced filter replacement.

The Quad Pulse Package PX

Compact filtration stages for pharmaceutical manufacturing processes:

Stage 1:

Primary filter with excellent filtration efficiency to remove the majority of the collected dust and prolong the service life of the second stage filter.

Stage 2:

HEPA filter to H14 providing 99.995% filtration efficiency to capture the finest, most harmful dust particles.

Compact design, small footprint

Space on the production floor and in the plant is at a premium. The ATEX-compliant explosion protection capabilities of the device enable the Quad Pulse Package to be conveniently installed with easy access for all maintenance functions.

High-performance, low noise level

The integrated fan can provide the suction required for most individual applications. At the same time, the unit is insulated to make it very quiet during operation.

Fan-less Model

A version for use with an external fan is available. This reinforced fan allows for operation as a high-vacuum filter, while stil maintaining all the explosion protection and containment features.

For Hazardous Dusts Requiring Full Containment

Compact and strong unit construction incorporates a unique HEPA filter design, with specialized materials from the aerospace industry, providing the following key advantages:

• The Quad Pulse Package HEPA filter captures the fine dust particles and is a tested flame and contamination barrier.
• Additional, expensive explosion safety devices are not required.
• The explosion shock pressure-resistant design maintains its integrity with no damage during an explosion event with ST2 organic dust.
• Compact unit with flexibility for indoor installation reduces the need for long duct runs.

• The Gold Series (GS) Camtain units can be used in a variety of pharmaceutical dust collector applications, including tablet presses, coating, fluid bed drying, spray drying, blending, granulation and general room ventilation.
• The GS Camtain is perfect for high-efficiency filtration where recovery of the product is not required.
• Safe-change containment systems are available for both the filter cartridges and discharge system underneath the collector. The cartridge change utilizes the safe-change filter replacement method while the discharge uses continuous liner technology.
• The GS Camtain can also support traditional dust collection for nuisance dusts and fumes that do not require full isolation and containment.
• Camfil APC has containment dust collectors for pharmaceutical applications in North, South, and Central America, Asia and Europe.

Benefits

• In the GS Camtain pharmaceutical dust collector, filter cartridges are sealed via an internal cam bar action, allowing convenient changeout through the safe-change filter replacement system.
• High-entry, cross flow inlet eliminates upward velocities that can hold fine particulates in the filter cartridges, reducing the re-entrainment of the particulate matter.
• Vertically arranged filters shed virtually all the particles versus horizontal filters which allow the particles to build on top of the filter in high dust loading applications.
• High-efficiency filters up to MERV 16 stop 99.99% of the dust at 0.5 microns!
• Specially treated filter media repels fine particulates for a lower pressure drop and longer filter life.
• Gold Cone® cartridge filter design provides 25% more media for long service life. HemiPleat® filter technology ensures uniform pleat spacing with synthetic beads that hold the pleats of the filter cartridge wide open.

Surrogate Tested Dust Collection System for Performance Verification

The Gold Series Camtain pharmaceutical dust collector has been independently surrogate tested for validated performance verification. A major pharmaceutical company's surrogate testing protocol was followed by an independently contracted, AIHA-accredited laboratory (Bureau Veritas) test.

Using 100% milled lactose as the surrogate, we collected over 75 area, personal and swab samples for both the safe-change filter replacement and the continuous liner discharge. The GS Camtain can handle risk-based category 3, 4 and 5 compounds with occupational exposure limits less than 1.0 mcg/m3 for an 8-hour time-weighted average. Full test report data is available upon request.

Health and Safety Considerations

Two key concerns are critical when handling pharmaceutical dusts: the potent, toxic or allergenic properties of the compound as it relates to personnel exposure and the explosion properties of the compound.

Health/Containment

The first issue involves understanding the toxicological properties of the material, reviewing the occupational exposure limit (OEL) and performing a risk-based exposure evaluation to determine the methods for proper control. In most cases, some level of isolation and containment is required due to the fact that the pharmaceutical dust is extremely potent while being captured in a non-production area. Therefore, it cannot be released into the surrounding environment.

In most cases, Camfil APC recommends a HEPA secondary polishing system. With HEPA backup systems and the dust collector, recirculation of the filter air back into the HVAC system is possible. This can significantly reduce energy costs while providing the necessary level of filtration for discharge air required by the EPA

Safety

The second concern involves deflagration and explosion potential. Control measures such as explosion venting, chemical suppression and isolation systems may be required depending on the physical characteristics of the dust relating to Kst, MIE and the location of the collector.

When explosion vents are required, they must be vented to the outside by either placing the collector outdoors or ducting the vent exhaust a specified distance through the building structure. To prevent outdoor or off-property exposure in the event of a dust explosion of potent compounds, either chemical suppression or containment designs for explosion and isolation valves are preferable to venting. The reason why is because these two protection options do not release materials to the environment.

Camfil APC recommends that an independent PE specifies what explosion protection is required for a given material as it relates to standards in NFPA, ATEX and the major insurance carriers.
