How to prevent deformation during transportation of large-size ULPA? Support and handling requirements

large sizeTo prevent deformation during transportation, ULPA filters need to be designed with packaging, force support and handling methods according to product requirements. The handling force should be applied to the permitted frame position, and the weight of the filter material or protective net should not be borne. The larger the size, the more obvious the risk of diagonal deviation of the outer frame and damage to the glue seams, and the higher the protection requirements during transportation and handling. Aili Industry isThe packaging design, frame manufacturing and complete machine assembly of non-standard ULPA filters can provide corresponding support to reduce the risk of deformation of large-size models during delivery.

1. Packaging should cover weak parts

Protect long edges, corners and media areas from internal supports pressing against the filter surface. Packaging posture and stacking conditions should be implemented according to the specific model instructions.

The long sides of large-sized filters are prone to bending during stacking, and the squareness of the outer frame will change after the corners are impacted. The internal support of the package should be at the frame position that allows stress, rather than pressing on the filter surface.

2. Use appropriate supports for transportation

Assess the size and weight, and use adequate personnel or appropriate workwear to avoid distortion caused by lifting only two corners. Prevent the outer frame from colliding when turning and passing through doors.

When only two corners are lifted, the weight of the filter element will cause diagonal distortion of the outer frame, which will affect the glue seam and sealing surface. Large-size models should use adapted tooling or multiple people to work together, and the stress points should be distributed at the permitted positions of the frame.

3. Inspect the goods before installation

Keep photos of the outer box and internal limit status, and check the diagonal lines, flatness and glue seams. If there is obvious impact or deformation, it should be isolated, evaluated and re-inspected.

Arrival inspection should begin before unpacking. The stress marks on the outer box are an important basis for judging transportation events. After unpacking, you should check the diagonal deviation and the flatness of the outer frame, not just the appearance of the filter surface. Ceiling project arrival inspection can be combined withthe FFU fan filter unit together.Check the installation interface of

4. Transport routes must be planned in advance

Before passing a large panel through a narrow door opening, a route should be planned to avoid tilting and squeezing on site only to find that support cannot be maintained. Turning radius, door opening height and elevator size all limit handling options.

When the route is not smooth, the site often has to be temporarily tilted or lifted sideways. This is a common cause of deformation of large-sized filter elements.

5. Related questions and answers

Can the filter surface be pressed down for transportation with a protective net?
cannot. The function of the protective net cannot be presumed to be load-bearing, and the entire filter element should be protected according to the packaging design. The appearance of the filter surface may not be obvious after being compressed, but the media and glue seams may have been affected.

Can large-size ULPA be carried by one person?
Not recommended. It should be based on the size and weight evaluation, use enough personnel or adapted tooling, and the stress point should be located at the allowable frame position.

When the product arrives, I find that the outer frame is slightly deformed. Can it still be used?
It should be evaluated in isolation, check diagonals, flatness, glue seams and sealing surfaces, and re-inspect if necessary. You cannot proceed with the installation based on appearance alone.
