What are the construction specifications of Filtotech Double Skin AHUs?

Filtotech AHUs feature double-skin panels (25mm to 50mm thickness) made of galvanized iron (GI) or stainless steel (SS 304/316). They include injected PUF insulation for thermal efficiency and an extruded aluminum profile frame for rigid, leak-proof performance.

Which filtration levels do your Air Handling Units support?

Our units are compatible with multiple filtration stages, including Pre-filters (10-20 microns), Fine filters (5 microns), and HEPA filters (0.3 microns) to meet ISO 14644-1 cleanroom standards and WHO-GMP guidelines.

Do Filtotech AHUs comply with Pharmaceutical Revised Schedule M?

Yes, our Air Handling Units are specifically engineered to meet Revised Schedule M and WHO-GMP requirements, ensuring proper air change rates, pressure differentials, and contaminant control in pharmaceutical manufacturing.

What is the difference between Belt Driven and Direct Driven AHUs?

Belt Driven AHUs offer flexibility in airflow adjustment via pulley ratios, ideal for larger systems. Direct Driven AHUs are more energy-efficient, require less maintenance, and are preferred for cleaner environments where belt dust must be avoided.

Does Filtotech offer custom AHU designs for space-constrained sites in Kolkata?

As a specialized manufacturer in Kolkata, we design custom Horizontal Floor Mounted and Ceiling Suspended units tailored to your site's physical dimensions while maintaining rated CFM and static pressure requirements.
