Our company's air motor stirrer, the "LZB33-B2.5" from Chuo Rika, is an oil-free type air motor stirrer that does not require lubrication. We offer arm-type, clamp-type, and sealed flange-type models. It operates quietly and is lightweight. Additionally, we have models like the "LZB33-B2.5-ETP," which features a type that does not scratch the shaft and allows only the shaft to move up and down. **Features of Chuo Rika's Air Motor Stirrer:** - Oil-free (no lubrication required) - Low noise - No fine particles (0.1 microns) - Lightweight - Operating air pressure: 0.2 MPa to 0.6 MPa *For more details, please refer to the PDF materials or feel free to contact us.*

The ultra-compact laboratory stirrer "LZB14-MG" features a magnetic drive, oil-free air motor, ultra-compact design, weighs 2.5 kg, and is explosion-proof. It is ideal for use in draft chambers and clean rooms. For more details, please contact us or refer to the catalog.

The oil-free air motor type "high-speed homomixer" has obtained patents in Japan, the USA, and Germany, and is currently receiving high praise from our clients. The central Rika Corporation homomixer features a structure with countless holes of a constant diameter in a rotating disk and a fixed disk, allowing for alignment of the holes through sliding rotation, which cuts the liquid as it passes through propelled by a propeller. Compared to other products, it has a larger liquid circulation cycle, and high frequency is generated between the fixed and rotating parts, further enhancing performance. The wetted parts are standard SUS316, and Teflon is also available. The propeller is made of Teflon. For more details, please contact us or refer to the catalog.

The newly developed product allows for stirring with a pipe as the stirring shaft, enabling liquid to be extracted through the upper rotary joint and pump of the shaft while stirring, and also allows for transfer. Liquid can be drained while the shaft is rotating, and it is fine even if it goes into a free spin state. Additionally, it is also possible to inject liquid in the reverse direction. Previously, the shaft was tightened with mounting set bolts, which often caused scratches on the shaft and led to issues with the shaft becoming stuck. However, with the adoption of the new ETP method in this product, there are no scratches on the shaft at all. For more details, please contact us or refer to the catalog.

The explosion-proof oil-less air motor stirrer with a helix type is a stirrer designed for explosion-proof specifications using an oil-less air motor. It can be easily attached to the helix of the tank lid. We offer various types tailored to the size of the helix. For more details, please contact us or refer to the catalog.

The magnetic drive vacuum stirrer adopts induction rotation (magnetic drive) and can be used without leaks even in high vacuum, as well as at atmospheric pressure and slight pressure. It allows for high-speed rotation and is characterized by its durability, as it does not use O-ring shaft seals compared to conventional products. It can be directly connected to the stirrers currently in use. It is ideal for vacuum distillation, evaporation, and concentration. For more details, please contact us or refer to the catalog.

Traditionally, the lightest powders, such as nano-carbon, did not yield good results even when various propellers were used for liquid dispersion. However, by using the original "cage-fixed propeller" from Chuo Rika Co., Ltd., which has undergone further improvements, dispersion can now be achieved much faster and mixing can also be done more quickly than before. There are two types of lump (raw powder) dissolution stirrers: a simple type and an improved type. For more details, please contact us or refer to the catalog.

The air motor explosion-proof stirrer is designed for safety in environments with organic solvents and explosive materials. It uses an oil-free air motor, allowing for variable speed control, with the rotation speed adjustable via a valve. Depending on the usage location, it can be piped for outdoor exhaust. There is no noise (using a silencer filter). For more details, please contact us or refer to the catalog.

We will introduce various components used in air motor stirrers. For more details, please contact us or refer to the catalog.

These are various optional components for the air motor stirrer. The size of the propeller is limited by the shaft diameter and length.

The 'Sealed Flange Seal Dust Collector' is an option for sealed flange type air motor stirrers. It catches dirt with a mesh, collects powder debris inside the dust collector, and, due to centrifugal force, expels moisture outside the dust collector. For more details, please contact us or refer to the catalog.

The air motor stirrer "elevating stand" is an air cylinder type elevating stand compatible with LZB33-B2, LZB42-B2, and LZB46-B2, with a height range of 1,272mm to a maximum of 2,072mm. The legs are covered with SUS304 plates. For more details, please contact us or refer to the catalog.

Traditionally, when using air motor stirrers or electric variable stirrers, the stirrer was installed on a stand and lowered into the stirring container for use, then lifted back up and secured with a lever after use. This required effort when the stirrer was used frequently, and in the case of the ETP method, cleaning was necessary. The newly released "Easy Lift Stand" allows for easy insertion into and removal from the container by simply pushing the stirrer up and down lightly with your hand. Models are available for LZB22-CB5, LZB33-B2.5, and LZB42-B2/LZB46-B2/LZB54-B2. For more details, please contact us or refer to the catalog.
