PORTA-FAB

PORTA-FAB is a manufacturer of modular in-plant structures, with a product line centered on steel-walled cleanrooms and related controlled-environment enclosures. The brand's cleanroom systems are supplied unassembled and are designed for on-site erection, allowing the enclosure footprint to be matched to available floor space and process layout. The current PORTA-FAB cleanroom range covers interior areas from 64 sq ft to 800 sq ft, with standard 10 ft ceiling heights and steel wall panels. Each unit in this series carries a Sound Transmission Coefficient of STC 31, which quantifies the assembly's resistance to airborne sound transmission and is relevant where the enclosure must isolate process noise from adjacent work areas or protect sensitive operations from external acoustic disturbance. The modular approach means panels, framing, and associated components are shipped as a kit; final particle-control performance depends on the filtration, pressurization, and sealing strategy specified for the installation. 3G Electric supplies PORTA-FAB cleanroom SKUs as part of its industrial equipment catalog, with multiple footprint options available from stock-listed part numbers. The range includes compact 8 ft x 8 ft and 10 ft x 10 ft units for single-operator or bench-scale work, mid-size 12 ft x 12 ft and 12 ft x 8 ft configurations, and larger 24 ft x 12 ft, 32 ft x 12 ft, 32 ft x 16 ft, and 40 ft x 20 ft structures for multi-station assembly, testing, or production cells. Because the cleanrooms ship unassembled, buyers should plan for site preparation, panel handling, and mechanical integration of any air-handling or environmental-control equipment. 3G Electric supports the line with SKU-level specification data, including manufacturer part numbers, wall material, sound transmission rating, and interior dimensions, so procurement and engineering teams can match a PORTA-FAB enclosure to a defined area and acoustic requirement. For applications where airborne particle levels, temperature, or humidity must be regulated, the PORTA-FAB steel-walled cleanroom provides the physical envelope; the environmental control system is specified separately to meet the target cleanliness class. The unassembled format also allows the structure to be moved through standard access routes and erected in existing facilities where a pre-assembled enclosure would not fit. 3G Electric's catalog lists PORTA-FAB cleanrooms by MPN, including 8CR88, 8CR812, 8CR1010, 8CR1212, 8CR1224, 8CR1232, 8CR1632, and 8CR2040, covering interior areas of 64, 96, 100, 144, 288, 384, 512, and 800 sq ft respectively. All units in this series share the same 10 ft height and STC 31 rating, which simplifies comparative evaluation across sizes. Buyers specifying a PORTA-FAB cleanroom should confirm the required interior dimensions, door and window locations, utility penetrations, and the intended cleanliness class, since these factors determine the supporting filtration and pressurization equipment. 3G Electric provides global supply and logistics coordination for PORTA-FAB orders, with documentation support for the part numbers listed in its catalog.

Frequently asked questions

Common questions about PORTA-FAB from 3G Electric.

What sizes are available in the PORTA-FAB modular cleanroom line?

The PORTA-FAB cleanroom series covers interior areas from 64 sq ft to 800 sq ft. Specific part numbers include 8CR88 (8 ft x 8 ft, 64 sq ft), 8CR812 (12 ft x 8 ft, 96 sq ft), 8CR1010 (10 ft x 10 ft, 100 sq ft), 8CR1212 (12 ft x 12 ft, 144 sq ft), 8CR1224 (24 ft x 12 ft, 288 sq ft), 8CR1232 (32 ft x 12 ft, 384 sq ft), 8CR1632 (32 ft x 16 ft, 512 sq ft), and 8CR2040 (40 ft x 20 ft, 800 sq ft). All units in this series have a 10 ft height and steel wall panels.

What does the STC 31 rating mean on PORTA-FAB cleanrooms?

STC 31 is the Sound Transmission Coefficient rating for the PORTA-FAB cleanroom wall assembly. It indicates the degree to which the steel-walled structure attenuates airborne sound between the interior and exterior. A higher STC value corresponds to greater sound isolation. STC 31 is consistent across the PORTA-FAB cleanroom part numbers listed in the 3G Electric catalog, so acoustic performance is uniform across the size range. This rating is relevant when the enclosure must limit noise transfer to or from adjacent production areas.

Are PORTA-FAB cleanrooms shipped assembled or unassembled?

PORTA-FAB cleanrooms in the 3G Electric catalog are supplied unassembled. The steel wall panels, framing, and associated components are shipped as a kit for on-site erection. This format allows the structure to be transported through standard doorways and service corridors and assembled inside existing facilities. Buyers should plan for site preparation, panel handling, and integration of any air-handling, filtration, or environmental-control equipment required to achieve the target cleanliness class, since those systems are specified separately from the enclosure itself.

What applications are PORTA-FAB steel-walled cleanrooms used for?

PORTA-FAB cleanrooms provide a controlled physical envelope for manufacturing, assembly, testing, and inspection operations where airborne particle levels, temperature, or humidity must be regulated. The steel wall construction and STC 31 rating also make the enclosures suitable for applications requiring noise isolation between the cleanroom interior and surrounding plant areas. Typical uses include electronics assembly, precision mechanical work, quality-control inspection, and laboratory or pilot-scale process work. The required cleanliness class determines the filtration and pressurization equipment specified alongside the enclosure.

How does 3G Electric support PORTA-FAB cleanroom orders?

3G Electric lists PORTA-FAB cleanroom SKUs with manufacturer part numbers, interior dimensions, wall material, and sound transmission ratings so engineering and procurement teams can match an enclosure to a defined area and acoustic requirement. 3G Electric coordinates global supply and logistics for PORTA-FAB orders and provides documentation support for the cataloged part numbers. Buyers should confirm door and window locations, utility penetrations, and the intended cleanliness class before ordering, as these factors affect the supporting environmental-control equipment.

What is the ceiling height of PORTA-FAB modular cleanrooms?

The PORTA-FAB cleanroom part numbers in the 3G Electric catalog, including 8CR88, 8CR812, 8CR1010, 8CR1212, 8CR1224, 8CR1232, 8CR1632, and 8CR2040, all have a 10 ft height. This uniform height simplifies comparative evaluation across the size range and allows consistent integration with overhead utilities, lighting, and air-handling components. Buyers should verify available ceiling clearance and access routes at the installation site, since the unassembled panels are erected on site and the finished structure requires 10 ft of vertical space.
