The broadest top-side hazardous-location FFU in this group, built around a 2 x 4 ft ULPA face.

2 x 4 ft broad ULPA footprint
120/240 V, 6.8 A, 820 W input
Top-side hazardous-location service arrangement

Giới thiệu Sản phẩm

The 2 x 4 ft model provides the largest accepted filter footprint in the top-side hazardous-location family. Its 23.72 x 47.63 x 19.86 in stainless cabinet uses a 120/240 V, 6.8 A, 820 W single-phase electrical package and top-side ULPA service. A non-sparking motor in a cast-iron explosion-proof housing supports the cited NEC Class I/Class II, Division 1 family construction, subject to evaluation of the complete installed configuration.

Các tính năng chính

Maximum classified-zone coverage

The four-foot filter face serves broader hazardous process areas with fewer module boundaries than smaller family sizes.

Defined electrical package

The listed single-phase input provides a concrete basis for power coordination in the large format.

Protected motor enclosure

The non-sparking motor is contained in a cast-iron explosion-proof housing within the cited product family.

Applications

Designed for larger classified pharmaceutical, chemical and aerospace clean areas requiring a broad filtered ceiling module. The large unit must be integrated with the site's area classification, ventilation strategy, electrical isolation, structural support and safe service route.

Solutions for Your Application

Several smaller hazardous-location modules would create extra joints and electrical connection points.Use the 2 x 4 ft unit to consolidate filtered coverage where the ceiling and power system support the larger cabinet.

The large motor load and classified wiring requirements can be underestimated.Coordinate the listed 6.8 A, 820 W package with the approved isolator, cable system and complete hazardous-area design.

Các tùy chọn có sẵn

Confirm area classification, 120 or 240 V input, ULPA filter and seal, stainless finish, ceiling support and top-side access. The entire installation must be assessed as one hazardous-location system.
