Hydraulic Dampers by ACE Facilitate Operation of Active Air Sampler

The environmental monitoring requirements of aseptic processing in the pharmaceutical and healthcare industries have become more and more demanding.

Pinpoint Scientific Ltd. designs and manufactures a range of high-quality microbial environmental monitoring products for pharmaceutical clean rooms and other highly-controlled environments. In order to make the daily work in clean-room environments of laboratories in the high-end food sector or medical technology, as well as in the pharmaceutical industry as easy as possible, the designers at Pinpoint Scientific have created a unique solution that has been thought through down to the smallest detail. During their search for high-quality components and while working on improving the operation of the lid with a quality solution for linear motion control the engineers contacted Applied Automation, one of ACE Fabreeka UK’s distributors. After considering all requirements and wishes, their field engineer recommended hydraulic dampers.


The decisive point for the use of hydraulic dampers was the customer's request for the lid of the sampler to be opened without any significant effort. Without this requirement, industrial gas springs, which can be precisely adjusted to the desired opening and closing speed by means of a valve that are offered made of stainless steel by ACE, would have been suitable motion control components. However, hydraulic dampers were chosen since they provide a constant feed rate combined with easy adjustability and only have to be tapped lightly to trigger the opening process of the lid. Another plus is the fact that hydraulic dampers enable a gentle closing process with additional damping.


ACE and Applied Automation were able to demonstrate another strong case in point: Because of the sensitive areas of application, ACE chose to fill the dampers with a specially refined vegetable oil with a very similar viscosity and service life. In the course of the product design, the engineers at Pinpoint Scientific contributed stainless steel sleeves with which the outer bodies of the hydraulic dampers that are made of coated steel are covered. On the one hand the stainless steel covers enable better hygiene owing to strict clean room requirements and on the other hand the material of the sleeves matches the rest of the unit.
