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.

As each clean room has a different allowance for particle size and varied cleanliness levels, there are various categories for each clean room. Some of them are described below:

Class 10:

A class 10 clean room chair is ideal for critical environments, and it is certified by a valid testing laboratory to ensure cleanliness.

The warranty is so good that it crosses the ANSI/BIFMA standards. It does not require any assembly tools because it has a simple design. The contamination control is excellent due to the separate filtration system in the backrest and the seat.

The cylinder for pneumatic control of the height adjustment comes with a lifetime guarantee.

Class 100:

The most striking feature of the class 100 clean room chair is its contoured back with a long-lasting scuff-resistant back pan. It also comes with complete certification and an additional filtration system for enhanced contamination control.


Class 1000:

It has all the features of other categories below it, but they are more suitable for a class 1000 clean room.

The warranty, certification, comfort level, and contamination control are not compromised.

What are the Components of a Clean Room Chair?

The main components of a Clean Room Chair are elaborated here:


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.



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.



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.



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

Average Pan Size

The pan size is adjusted so that a petite and average body-sized person can fit in perfectly. It is neither too tight nor too big for most individuals.


Sturdy and Stable

It is made up of electropolished 316L stainless steel. It has improved stability against most corrosive and reactive agents like acids and chemicals commonly used in such working environments. The electropolished finish also gives a cleaner and more aesthetically pleasing look.


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.

How to Choose Suitable Clean Room Chairs for your Clean Room?

To choose the most suitable Clean Room Chair for your application, you must consider the following factors:


The Attire of the Workers

The attire and the fabric of the worker’s clothing significantly impact the chair selection. If the worker is wearing a clean room jumpsuit and is using a forward seat tilt for better posture, he will end up experiencing more sliding downwards due to the forward tilting and slippery gown.


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.
  • The lower part of the backseat shall be slid into the control mechanism. The height can be adjusted according to the choice, and then it can be tightened through the handwheel.

For 4200, 4600 Series Chairs:

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.
  • The back center of the chair can be removed. This allows lifting any pressure from the lower part of the spine, permitting a more comfortable posture. It is ideal for people with already facing lower back problems.
  • You can get the single curve backrests for people suffering from spinal fusions, scoliosis, etc.
  • The standard arm adjustment range can also be modified.
  • The armrest position can be adjusted according to your choice and requirement.


What are the Precautions Related to a Clean Room Chair?

The precautions related to a Clean Room Chair are written below:

  • Don’t use any corrosive or reactive material directly on the chair’s metal.
  • Avoid standing on the foot ring to prevent breaking due to unequal weight distribution.
  • Please don’t go overboard with the tight ending of nuts and bolts, and keep adjusting them to allow better aeration. It will prevent the oxidation of certain parts.
  • Follow all the protocols of the clean room to avoid any contamination.


What are the Testing Protocols for a Clean Room Chair?

Testing is a crucial step before purchasing your Clean Room Chair, and therefore, it must be conducted with complete protocols. Stated below are a few essential tests and certifications:


ESD Test

The performance of the ESD test must be less than 10e8 ohm. As it is a safety mechanism, it must be tested before shipping.



You can get a significant increase in the productivity of your application by paying due attention to the comfort and convenience of the workers. Using the right Clean Room Chair can work better, protect the controlled environment, and save yourself from exhaustion and long-term backbone disease.
