Filtration hood without connection

The StemAids Filtration Hood Without Connection Smart 392 / 483 / 633 / 714 is a ductless laboratory filtration hood designed for safer handling of compatible chemical vapours, solvents, acids, formaldehyde, ammonia vapours, powders, and particles when fitted with the correct filter configuration. It is suitable for schools, colleges, chemistry laboratories, pharmaceutical labs, research facilities, quality-control laboratories, and institutional science laboratories.

Product Description

The StemAids Smart Filtration Hood is designed to protect laboratory users from inhalation exposure by capturing contaminated air inside the hood and passing it through application-specific filters. Since it works without external duct connection, it supports flexible installation, reduced ducting cost, and easier laboratory layout planning.

The Smart 392, 483, 633, and 714 models are available in different working widths to match small, medium, and large laboratory applications. These hoods can be configured with activated carbon filters for chemical vapours, HEPA H14 filters for particles, ULPA U17 filters for high-efficiency particle filtration, or combined filtration depending on the laboratory process.

Important Note: This is a chemical filtration hood, not a biological safety cabinet. It should not be used for infectious biological materials, radioactive substances, explosive vapours, or unknown high-risk chemicals unless the exact configuration is approved by qualified laboratory safety personnel.

• Do not use for unknown, explosive, radioactive, highly toxic, or infectious substances without formal risk assessment.
• Do not exceed the chemical quantity or filter capacity recommended by the safety assessment.
• Check airflow before each use.
• Replace saturated, expired, clogged, or incompatible filters immediately.
• Do not block the sash opening, air intake, exhaust area, or filtration module.
• Wear suitable PPE such as gloves, goggles, lab coat, and respiratory protection where required.
• Keep ignition sources away when working with flammable vapours.
• Follow SDS instructions, institutional safety rules, and local laboratory regulations.
• Allow only trained personnel to install filters, service the hood, and approve chemical use.

FAQ

1. What is the StemAids Smart Filtration Hood used for?

It is used for ductless filtered handling of compatible chemical vapours, solvents, acids, powders, particles, and laboratory reagents.

2. Does this hood require external ducting?

No, it is a filtration hood without external connection. It filters contaminated air and returns filtered air to the laboratory room.

3. Which models are included in this range?

The range includes Smart 392, Smart 483, Smart 633, and Smart 714 models.

4. What is the difference between 392, 483, 633, and 714?

The main differences are working width, airflow capacity, power consumption, and internal working space. Larger models are suitable for larger apparatus and higher workflow capacity.

5. What filter types can be used?

Filter options include activated carbon filters for gases and vapours, HEPA H14 filters for particles, ULPA U17 filters for high-efficiency particle filtration, and combined filtration systems.

6. Can it be used for solvent vapours?

Yes, compatible solvent vapours can be handled when the correct activated carbon filter is selected and the chemical quantity is within approved safety limits.

7. Can it be used for powders?

Yes, powder handling is possible when a suitable HEPA or ULPA particulate filter is installed and the application is approved by laboratory safety personnel.

8. Is this hood a biological safety cabinet?

No, this is a chemical filtration hood. It should not be used for biological containment unless the exact system is certified for that purpose.

9. What is the air face velocity?

The reference air face velocity is 0.4 to 0.6 m/s.

10. What power supply is required?

These Smart filtration hoods commonly operate on 220 V, 50–60 Hz supply, depending on supplied configuration.

11. How often should filters be replaced?

Filter replacement depends on chemical type, concentration, quantity, operating hours, saturation indication, and laboratory safety assessment.
