is not an independent function but a phenomenon brought about by its special buffer design. Its core purpose is to solve the contamination problem of the ordinary Pneumatic cylinder at the end of the stroke.
I. Pollution Sources of ordinary Pneumatic cylinders
At the end of the stroke, the piston of a common Pneumatic cylinder will violently strike the end cover. The gas in the closed cavity of the Pneumatic cylinder is rapidly compressed and then ejected at high speed from the main exhaust port. This airflow will carry the lubricating oil mist and metal friction particles inside the Pneumatic cylinder, causing fatal pollution to the clean room environment.
Ii. Working Principle of "Low-Speed Overflow
1. Special structure
When the piston approaches the end of its stroke, it will be inserted into a buffer sleeve with precise micron-level grooves.
2. Create back pressure
The main exhaust duct is cut off, and the gas can only be slowly discharged from these extremely fine grooves. This process creates a controllable back pressure in the closed cavity, gently stopping the piston like an "air hand", causing it to decelerate smoothly until it comes to a stop and achieves a shock-free "soft landing".
3. Low-speed exhaust
The gas being discharged has its flow rate and volume significantly reduced as it passes through the narrow grooves, becoming slow and uniform. This low-speed airflow no longer has the kinetic energy to carry out the internal particles, thus achieving a "clean" exhaust.

Iii. Treatment and Design Advantages of Overflow Gas
The gas discharged at this low speed can be directly dispersed in the clean room, meeting the high cleanliness standards. For extremely harsh environments, the Pneumatic cylinder also has an external exhaust port, which can export the gas to the outside of the clean area.
This design not only eliminates exhaust pollution but also reduces the wear of the Pneumatic cylinder itself by avoiding rigid impact, further reducing the generation of particulate matter from the source and forming a double guarantee.

An excellent Pneumatic cylinder is the carrier of its advanced design concept inside. The Sunway 10CDM2BZ series clean mini Pneumatic cylinder is precisely the epitome of such technologies. It adheres to a professional, clean design. Its internal buffer mechanism can effectively achieve low-speed overflow, ensuring a smooth and low-impact stop at the end of each stroke during frequent reciprocating motion, and reducing exhaust pollution to an extremely low level, reliably guaranteeing your clean environment grade. Choosing it means choosing a clean guarantee for your equipment.
"Low-speed overflow" is a concentrated embodiment of the design philosophy of clean Pneumatic cylinders. Through ingenious mechanical design, it transforms the inevitable physical processes (braking and exhaust) into means to ensure cleanliness, and is a model of engineering technology serving specific needs.
