- General room ventilation
Gold Series Camtain for Pharmaceutical Manufacturing Applications
- 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.
- 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.
The Gold Series contained dust collector is a winner for our pharmaceutical applications. It is way ahead of the curve of anyone in the dust collection industry. The results from the potent compound surrogate test are very positive. Nice work!

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. You can download a summary of the surrogate test report now.
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.
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.
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.

Proper Application of the Gold Series Camtain
Camfil APC has an entire team assembled specifically to support the pharmaceutical market. Qualified engineers will work with you to properly apply a Gold Series Camtain pharmaceutical dust collector on your application. Below is a sample of questions/considerations:
- Is the material being collected considered a hazardous material? If so, what is the occupational exposure limit (OEL)?
- What is the source of the dust?
- If the dust is coming off of a process machine, who is the manufacturer?
- What is the air volume that the collector is required to handle?
- What is the estimated dust loading?
- What are the hours of operation?
- What is the required total static pressure the system will need to withstand?
- Will the collector be located indoors or outdoors?
- What is the electrical classification of the room for the collector?
- What are the operating and maximum temperatures?
- What is the relative humidity of the airstream going to the collector?
- What are the Kst value and Pmax of the dust going to the collector?
- Will you be using explosion vents or an explosion suppression system?
- If they want a suppression system, do we need to provide this?
- Do they need isolation for the ductwork? Inlet and Outlet?
- If they are venting, are they venting through a wall (horizontally) or ceiling (vertically)?
- What is the length of the explosion vent ductwork needed?
- Is containment specified? Is it for both the filter change and discharge?
- If the unit is indoors, what are the dimensions of the room?
- Are pre-filters and/or after-filters required? Do they need to be safe-change?
- Do we need to supply the fan (pressure blower)?
- Does the customer currently have dust collectors? Whose? Are they contained?
- What do they like/dislike about collectors/collector manufacturers with which they have experience?
