Abstract
The utility model discloses a novel lower replacement type fan filter unit (FFU) and relates to the technical field of purification equipment in air purification industry. The novel lower replacement type FFU consists of a high-efficiency filtering net (1), a sealing strip (2), an FFU box (3), nuts (4) and fixing screws (5), wherein the sealing strip (2) is arranged on the high-efficiency filtering net (1); two nuts (4) are respectively arranged on a baffle at the bottom of the FFU box (3); and the high-efficiency filtering net (1) is connected to two nuts (4) on the FFU box (3) through two fixing screws (5). The novel lower replacement type FFU can replace the filter from the lower part and is low in replacement difficulty and good in sealing effect.
Description
Technical field:
The utility model relates to purification technology field in the air purification industry, relates in particular to a kind ofly to change formula FFU under novel.
Background technique:
At present FFU adopts changes the formula process engineering on being; Promptly, the perforate of color steel top board puts into fixing frame to high efficiency particulate air filter earlier after receiving the limit; Be held on the FFU casing on the filter again; Utilize the casing deadweight to compress the Stamping Steel Ribbon that carries on the filter and guarantee whole tightness, must stand in the time of will changing filter by the time to raise earlier on the ceiling board top and remove the FFU casing, could change original high efficiency particulate air filter then; Can't stand in and change filter in the dust free room, or can't guarantee its tightness in indoor replacing.
The model utility content:
The purpose of the utility model provides a kind ofly changes formula FFU under novel, and it can change the low and good sealing effect of difficulty from following replacing filter.
In order to solve the existing problem of background technique, the utility model is to adopt following technological scheme: it is made up of efficient filter screen 1, Stamping Steel Ribbon 2, FFU casing 3, nut 4, retaining screw 5; Stamping Steel Ribbon 2 is installed on the efficient filter screen 1, and two nuts 4 are separately positioned on the baffle plate of FFU casing 3 bottoms, and efficient filter screen 1 is connected on two nuts 4 on the FFU casing 3 through two retaining screws 5.
The utility model changes the formula process engineering under adopting, and during replacing retaining screw 5 is screwed off, and just can take down efficient filter screen 1, and it is convenient to change.
The utility model can be changed the low and good sealing effect of difficulty from following replacing filter.
