HEPA Filters Supplier In Sri Lanka – HVAC, Cleanroom & Industrial HEPA Selection | Hindustan Filters
Quick answer: If you need a HEPA Filters Supplier In Sri Lanka, start with the application and the equipment drawing, not only an H13 or H14 label. Hindustan Filters handles enquiries for HEPA filtration used in AHUs, cleanrooms, laboratory ventilation and specified healthcare or pharmaceutical systems. A suitable quotation needs the filter grade, actual size, rated airflow, resistance, frame and seal details. A HEPA filter traps fine airborne particles; it does not, by itself, control gases or guarantee a cleanroom classification.
Quick specification check: Under EN 1822, an H13 filter has at least 99.95% overall efficiency at MPPS; H14 has at least 99.995%. These are filter-class definitions, not a claim that every Hindustan product has been independently tested to that class. Ask for the test method and supporting documentation for the exact model being quoted. For Sri Lankan projects, size, airflow and a leak-tight fit are just as important as the efficiency label.
HEPA Filter Specifications to Confirm Before Ordering in Sri Lanka
Common enquiry dimensions include 24 × 24 × 12 inches and 24 × 48 × 12 inches, but these are examples, not universal AHU sizes. Check the actual depth, frame and gasket measurements against the equipment drawing. Even a small mismatch may allow bypass air.
📌 Details to Include in a HEPA Filter Enquiry:
- Filter Class: State the required H13, H14 or project-specified classification.
- Exact Size: Share width × height × depth in mm or inches; avoid relying only on a nominal size.
- Rated Airflow: Provide the design airflow or equipment requirement.
- Pressure Drop: Confirm the acceptable initial resistance at the stated airflow.
- Frame: Specify the required construction material according to the installation.
- Media / Pleat Design: Deep-pleat or mini-pleat configuration should suit the housing and airflow requirement.
- Seal: Confirm gasket position, gasket type or gel-seal requirement.
- Testing / Documentation: State any project-specific test report, scan-test or documentation requirement in the enquiry.
Where HEPA Filters Are Used in Sri Lanka
- Pharmaceutical processing and cleanrooms where validated air quality is required
- Hospital and healthcare ventilation where HEPA filters are specified by the facility design
- Controlled cleanrooms and critical manufacturing areas where HEPA filtration is specified
- Laminar Air Flow (LAF) hoods, biosafety cabinets & pass-through boxes
- Food and beverage processing areas with controlled air-quality requirements
- Electronics and precision manufacturing areas with controlled particulate requirements
- Commercial and industrial HVAC and air-handling systems
💡 Practical Sri Lankan Buyer Note:
A frequent enquiry problem is simply “H14, 10 pieces.” That does not tell the supplier which housing, seal or operating airflow is involved. Include the filter label, a photo of the installation and the measured dimensions. If the filter is going into a validated cleanroom, ask your quality team which documents and on-site integrity checks will be required after fitting.
Common HEPA Filter Configurations for Sri Lanka Projects
There is no one-size-fits-all HEPA cartridge. Match the construction to the housing, maintenance access and design airflow. Common configurations to discuss are:
1. Deep Pleat HEPA Filters (24 x 24 x 12 Inch)
A traditional pleated construction used where the housing and airflow specification calls for a deeper filter. Confirm the exact depth, separator construction and rated airflow before replacement.
2. Mini Pleat HEPA Filters
A compact pleat arrangement commonly considered where a larger media area is required within a relatively shallow or space-conscious configuration. Pressure drop should always be compared at the same airflow.
3. High-Temperature HEPA Filters
For processes involving elevated temperatures, standard adhesives and gaskets may not be suitable. Specify the continuous and peak temperatures, exposure duration and required frame and sealant performance; request the model-specific temperature rating before selection.
4. Gel Seal & Custom Size HEPA Filters
Gel-seal and custom-size filters are useful when the terminal housing or OEM equipment requires a specific sealing interface or non-standard dimensions. A drawing or clear photograph of the existing installation can prevent specification errors.
How to Choose a HEPA Filters Supplier In Sri Lanka
- ✅ Specification clarity – The quotation should identify filter class, dimensions and construction instead of relying on a generic HEPA description.
- ✅ Airflow and pressure-drop data – Compare filters at the airflow your system actually uses.
- ✅ Correct sealing arrangement – Gasket location and gel-seal requirements can be as important as the filter grade.
- ✅ Suitable frame construction – Select the frame according to the AHU, terminal housing and environmental requirement.
- ✅ Required documentation – Ask for the documentation specified by your consultant, validation team or project before ordering.
- ✅ Replacement compatibility – For existing systems, share the old filter label, exact measurements and housing photographs where possible.

What to Send Hindustan for an Accurate HEPA Filter Enquiry
- 📐 Exact dimensions – Width, height and depth of the required filter.
- 🌬️ Airflow data – Rated airflow and any stated pressure-drop limit.
- 🛠️ Construction details – Required frame, pleat type and gasket or gel-seal arrangement.
- 📄 Project requirement – Filter class and any testing or documentation requested by the consultant or end user.
- 📷 For replacements – A photo of the existing filter label and housing is often surprisingly useful.
🇱🇰 HEPA Filter Enquiries from Across Sri Lanka
For HEPA filter requirements in Colombo, Gampaha, Kandy, Galle, Kurunegala and other parts of Sri Lanka, share the project location and technical schedule so supply options can be discussed rather than assumed. Coastal humidity, the condition of the air-handling unit and access for filter installation may also affect the specification.
Suggested technical-team guidance (for Hindustan to approve): “A photo of the old filter label and the sealing edge often saves more time than sending just the H13 or H14 grade.”
Frequently Asked Questions (FAQs) – HEPA Filters Supplier In Sri Lanka
What should I include in a HEPA filter enquiry for Sri Lanka?
Provide dimensions (including depth), quantity, rated airflow, specified H13 or H14 class, allowable pressure drop, frame type, gasket or gel-seal arrangement, destination and required test documents.
What is the difference between H13 and H14 HEPA filters?
Under EN 1822, H13 has a minimum overall efficiency of 99.95% at the most penetrating particle size (MPPS), while H14 has 99.995%. Choose the required class and confirm airflow and pressure drop.
Why does initial pressure drop matter for an AHU HEPA filter?
Initial pressure drop is the airflow resistance of a new filter at a stated flow rate. An unsuitable resistance can reduce airflow or increase fan demand; compare alternatives at the same operating flow.
Can I order a custom-size replacement HEPA filter?
Custom requirements can be reviewed from a drawing, old filter label and clear housing and seal photographs. Confirm dimensions, construction and availability before ordering.
Are 24 x 24 x 12 inch HEPA filters a standard fit for all equipment?
No. These are common nominal dimensions, but actual depth, frame tolerance and gasket position vary. Measure the filter and check the AHU or terminal-housing drawing.
Do cleanroom HEPA filters need testing after installation?
Where the cleanroom validation plan requires it, installed-filter integrity or leak testing is performed after fitting. A factory filter test does not replace installation qualification.
Can HEPA filters remove odors or chemical vapors?
HEPA media is intended for airborne particles, not gases or odors. Applications involving vapors may need separately specified gas-phase filtration such as activated carbon.
Which details matter for shipping HEPA filters to Sri Lanka?
Confirm packing protection for fragile media, delivery destination, quantities, required documentation and the commercial terms with the supplier before confirming the order.
Need HEPA Filters for a Sri Lankan Project or Replacement?
Contact Hindustan Filters with your filter schedule or a photograph of the existing unit. Include size, quantity, desired H13/H14 class, rated airflow, frame and seal type, destination in Sri Lanka and any specified test documents. Ask the team to confirm technical suitability, availability and quotation details before placing an order.
