CD-230V EX (CFB) PHARMA

ATEX II 1/2GD indicates certification for both gas and dust atmospheres. The “II” refers to electromagnetic emission–this is not a new ATEX application but a gas group where IIA is lowest energy and IIC is highest (hydrogen environment). The “1” means the vacuum is approved for Zone 1 (where gas can occur during normal operation). “2GD” means Zone 2 (gas) and Zone 21/22 (dust). CD-230V EX (CFB) PHARMA carries II 1/2GD, meaning it meets requirements for both Zone 1 and Zone 21–a higher rating than II 2GD, which permits only Zone 2 and Zone 22.

HEPA H14 captures 99.995% of particles at MPPS (Most Penetrating Particle Size). ULPA U15 captures 99.999%–a 4x further reduction. When handling high-potency compounds with exposure limits below 1 µg/m³, even small percentage gains are critical. ULPA U15 filtration provides the extra safety margin required by top-tier pharmaceutical standards and reduces carcinogenic or teratogenic exposure to the absolute minimum.

CFB stands for Conductive Filter Bag–a sealed conductive pouch that holds all recovered material from intake until change-out. In traditional vacuums, operators must handle filters or bags when they are full, exposing them to dust. With CFB, the bag is mounted at the tank base, and when change-out is needed, the entire bag is removed as one sealed unit without dust release to the room. This drastically cuts inhalation exposure and eliminates cross-contamination risk between batches.

Yes. The vacuum is designed for dual duty. In production zones it can recover waste dust from tablet presses or capsule fillers. The same machine can then be used for equipment cleaning–for example, dust-off operations on API residue from surfaces–without changing tools. The ATEX rating ensures it can be co-located with production without additional ventilation or segregation.

68 dB(A) is extraordinarily low for a 1.5 kW explosion-proof vacuum. It is achieved through an integrated acoustic muffler that routes exhaust air through sound-absorbing material before release. In practical terms, an operator can work all day without hearing protection–exposures below 80 dB(A) are not occupational health hazards under EU regulation. This makes the vacuum attractive in pharma environments where continuous use is expected.

All metal components–tank, motor bracket, wheels, hoses–are stainless steel Type 304 and connected with conductive fasteners. Electrostatic resistivity below 10 ohm means static charge drains continuously to ground without building up. In explosive atmospheres (Zone 1 or Zone 21), even small static discharges can ignite gas or dust. A vacuum with resistivity below 10 ohm can never be the ignition source.
