Workbench

Product information

1、Two double inlet ai↓§<r blowers are used in¶π$≈ the top chamber,which makes t♣β"₽he air outlet area larger while t​ >€he clean and effective area greatly i₩✔♣φmproved.

2、The fan circulation¥≥πδ on both sides of the u↕✘pper and middle chambers accelerate'±<s the flow of wind velocity inside th€ε✔e chamber,avoids looping deσ±'ad angles,and makes tε•he flow even and better.

3、The multi-wing impell€∞ δer is used in the lower¶♣✔ chamber to increase tσ≈he circulating wind speed and a★Ω'♠ir pressure. With a high effic♥φiency air filter,the cleanliness i☆×δ↓s better.

4、Double fluorescent β♣lamps are installed on the ​β top of the table.

5、When the lower chambe♦​£&r door is open,the motor stops automat' ☆ically, in order to pr↑↑£αevent external dust from enter ♣₩$ing the chamber.

1、Function of dust-free workbench

The Clean Bench is a & ÷αnbsp;machine that provides a lo✘₹£cally high cleanliness environment thro¥✘♦ugh an efficient filtration system. It÷≈♦£ is mainly used to cl♥πean, place and pretreat substrate÷©εs before coating, ensuring tha ₽★t the substrate surface is →≠free of dust, particles orλ​​₹ organic contaminants,♣​ thereby improving cΩ♣"←oating quality and a‍↓dhesion.

2、Core types and application scenario→Ω±₹s

Vertical laminar flow clean table

Air flow direction: The air flo"♥¶ ws vertically from top to botto"∏↕≥m and is purified by high eff©>iciency filter (HEPA/ULPA) to for¶π✘m a clean area.

Application scenario: Suitable for fine≠¶✘♦ cleaning of substrates before c♣δ oating, pre-treatment of optical lenses€↔✔λ or semiconductor wafers.

Horizontal laminar f§↕low clean table

Airflow direction: Air flows ↔α∑ horizontally, from one side of the o™®perator to the other.

Application scenario: It is suita≈&ble for the pre-coating pr•↓→ocess where materials need to be frequ≈≥ently removed and placed (such as tεπ€emporary storage after metal parts >‌♥&are cleaned).

Biosafe dust-free workbe' nch

Features: Equipped with UV gerΩ​micidal lamp and negative pressu₹λ≈re system to prevent cross co≈'ntamination.

Application scenario: ™♠Processing of biosensit>✘¥ive materials (such as coati₹™≠ng substrates for medical devi‌©ces) before coating.

4、Operation specifications b☆¥ δefore coating

Preparation for startup:

Start the fan and UV lamp 30 minut πes in advance to ensu♦§≈₩re the stability of the clean δ∞area.

Use a particle counter t★✘←δo check the cleanliness of the w←£∑ork area (target ≤100 level).

Substrate treatment steps:

Pre-cleaning: Wipe the subst↕↕φ¶rate surface with a dust‍×←Ω-free cloth dipped in♥≈ high purity isopropyl <★alcohol (IPA).

Placement: Base material in the c‍✔♠enter of the table, avoid near π↓the edge (airflow disturbanc ♦αe area).

Electrostatic elimination: Use ion≠←$↔ fan or electrostatic brush to eliminat$<≤e static electricity on the surΩ₽©face of the substrate to preveλγ‍₽nt adsorption of particles.

Personnel operation requirements:

Wear dust-free clothing, gloves >→and masks to avoid h→'uman dander or respiratory coλ£ntamination.

The operation is light and s≥γ•low to reduce airflow disturbance.

5、Equipment selection sugges±♣ ¥tions

Select according to cleanli♥₩ness requirements:

Optical coating: ISO Class 3 (Class 1) &•↑required, ULPA filter + ve ₩×rtical laminar flow re""‌commended.

Industrial coating: ISO &®5 (Class 100), optional HEPA≠↓α© filter + horizontal lamina  Ωr flow.

Select by process compatibility:

For integrated ion fan or UV  ₽₽sterilization, choose a modular designφε× table.

If the size of the substrate is larg✘¶e, the option is to w§♣♣‌iden and deepen the working area (su®£ch as 1800×800×800mm).

6、Maintenance

Daily maintenance:

Clean the table afte∏↑r daily use and wipe the resi↕'αdual solvent with a dust-free cloth.←‍↔

Monthly monitoring of wind speσ↑ ed and pressure differen₹'★ce to ensure the uniformity of↓€® air flow.

Filter replacement:

HEPA filter: Replace every ¶ε‍1-2 years or when the press←$ure difference is ≥250Pa.

Pre-filter: Clean or replace every 3-6 $→months.

Calibration and Cert≈←ification:

Every year, a third party testing orα'↑ganization is commissi®Ω☆¥oned to conduct cleanliness certificati✘♥§on (ISO 14644 standard ®↑<).

7、Precautions

Prohibited operation: Act‍¶∏÷ivities that produce dust (such as g≤©>rinding and cutting) in a dust-fre§•e workbench.

Emergency treatment: ₩™♦≠If accidental leakage of che ✘‍mical reagents, immediate★σ×ly shut down the fan and thoroughly cle£¥₩an.
