What are the Different Categories of Clean Room Chairs?

The different categories of a Clean Room Chair based on the fabric material are given below:

Static Dissipative Fabric

The use of static dissipative fabric ensures additional protection due to the safe discharge of free active charge. It tends to flow towards the ground due to the particular flooring and the metallic component in the clean room floor. The surface resistivity of this category is almost ten ^5 to 10^9 Ω (ohms).

ESD Vinyl Fabric

It ensures easier cleaning and enhanced chemical resistance and makes sure that the free current is effectively transferred to the grounded floor.

Back

The conductive vinyl or fabric covers the rear and front panels. Many rows of staples secure the fabric through the copper bands, and metal T nuts secure the copper bands. The back bar is connected to the t nuts through metal screws.

Back Bar

It acts as a passage to allow the flow of electrical discharge as it is a steel bar and has a sturdy assembly. It is connected to the metal frame as well.

Seat

It is intricately designed and constructed with the help of conductive or vinyl fabric, T nuts, metal screws, and multiple copper bands.

Mechanism Control

It works by using a metal frame that allows the gas to lift.

Gas Lift

A spring plunger and a ball allow constant contact between the cylinder and the gas lift mechanism. It helps in the gas lift as well.

Base

The base is in direct contact with the gas lift and anchors the chair onto the floor. The angle and construction of the base allow stability and balance.

Casters

The glides and ESD casters are conductive and therefore valuable for some applications.

Smooth Finish

It gains a bent shape and smooth surface with careful design and continuous welding. As there are no cracks or crevices, there is additional protection from the growth of algae, mold, and bacteria on the chair.

Compliance With ISO Classification

The material used in the construction of the different parts, including the seat and the legs, is tested and proved safe for the ISO classification it is to be used.

Therefore, for each classification, the characteristics of the chair might vary. However, the stability and the properties to maintain the cleanliness level remains the same.

IEST, ASTM cGMP, and ISO 14644-1 Certification

As it is constructed according to cGMP, IEST, ASTM, and ISO 14644-1, there is a proper certification as proof that it won’t be harmful to your application that needs complete sterilization.

Sturdy and Anti-Skid Base

The base is either 3-legged, 4-legged, or 5-legged and can be chosen according to the design preferences. It is made of solid material to bear the individual’s weight and the chair.

High-Quality Hardware

All the hinges, glides, latches, and ports are carefully chosen for increased reliability and strength. Since these hardware pieces make or break the piece of furniture, they hold great importance. These are repeatedly tested and carefully fitted.

The purpose is to obtain comfortable seating for long hours to maintain cleanliness.

Applications of a Cleanroom Chair

What are ESD Clean Room Chairs?

An ESD Clean Room Chair stands for electrostatic dissipation that controls the static charge and comprises particular components, bases, and fabrics.

They use specially designed casters to reduce the static charge that might be generated in an area by sitting on the chair. Then it is discharged safely through the ground.

It gives a safe passage for the flow of the static discharge, which might be harmful to your application.

The industries dealing with the static charge problem are mainly the following:

• Large PCB manufacturing companies and the factories that deal with the production of other electronic components.
• Technical production facilities related to education, research, and science experimentation.
• Medical electronics and hospital areas with well-developed medical machinery.
• Many types of clean rooms and research sites such as laboratories.

Time Duration

Evaluate the average time a worker spends sitting while working. It will help you choose a more appropriate option since you can select based on comfort and posture. The chair shall have a design that supports the body and equally distributes the body weight to allow stability and comfort.

Clean Room Classification

As each clean room has its preferences and protocols, it is essential to comply with the rules. Therefore choose the chair according to the required class.

Certification and Approval

All the verifications and factory testing must be complete and follow the given protocols. It helps you stay safe and enjoy a well-protected experience in terms of your safety and the clean room safety.

Ergonomic Design

This implies that the design is more suited for the user’s benefit working in an environment. As a clean room is highly controlled, it needs ergonomic controls.

No Addition to Contamination

The surfaces are smooth, and the materials are non-chapping and stable. Thus there is no risk of linting and chipping.

Maintenance Requirement

As the back is self-filtering and doesn’t allow particulate matter to clutter and clog it, you don’t need an external mechanism for cleaning.

The surfaces can be cleaned and disinfected quickly using convenient agents like alcohol, chlorine, etc.

How to Assemble a Non-Tilt and Tilt Clean Room Chair?

To assemble a non-tilt and tilt Clean Room Chair, follow the given instructions:

• Carefully unpack the package and ensure that you have received all the components, nuts, and screws.
• Start by inserting the glides into the casters on each leg of the base.
• The tubular part of the foot ring shall be held upwards and tightened with the cylinder. Make sure it is secure in its place by tightening the handwheel.
• Now slide the cylinder into the upper part of the center of the base.
• Place the seat and the control mechanism of your so far assembly. To tighten it further, you may sit on it to apply pressure through your weight.
• Don’t forget to remove the white washer and handwheel from the backrest hinge.
• The back bar shall be aligned with the hinge assembly.
• Secure it by placing the washer on the back bar and turning the handwheel.

Although there are no armrests, the metal mushroom glides have a rubber cushion. The diameter is one inch.

Drag Chains

Drag chains make sure that the connectivity between the flooring system and the chair is maintained. They allow continuity from the ground point if the casters fail to perform their action. It happens when the casters are dirty. The condition for drag chains is that the floor must be conductive.

In-Seat Filtration and Particle Traps

As 25% remain suspended in the air when a person sits or walks, it is essential to prevent contaminated or particle-laden air from passing through the chair’s cushion.

The media of the chair, predominantly polyurethane, allows only particles smaller than 0.1 microns to pass through it. This helps in maintaining a rigorous environment in the clean room.

How to Customize your Clean Room Chair?

To customize your Clean Room Chair, you may consider the following points:

• Reduce or shorten the width and height of the seat.
• The shape and softness of the heart can be modified by using foam and cutting it according to the body type.
