Absolute Filtration for Sub-Micron Precision

In the semiconductor industry, a single 0.1μm particle or trace of acid gas can destroy millions in wafer yields. DTAF engineers ultra-low resistance PTFE filters, FFU modules, and AMC chemical systems to protect your most critical ISO Class 1-5 ambientes.

The Threats to Your Yield Rate

Modern microelectronics manufacturing faces three critical airborne enemies. We neutralize them all.

Sub-Micron Particulates

As node sizes shrink below 3nm, even 0.1μm particles cause fatal defects on silicon wafers. Standard HEPA is no longer sufficient; ULPA integration is mandatory.

Airborne Molecular Contamination

Acidic/alkaline gases and VOCs from fab processes cause severe lens hazing and wafer corrosion. Physical dust filters cannot stop these chemical threats.

Massive Energy Consumption

Cleanrooms require thousands of Fan Filter Units running 24/7. High-resistance filters force motors into overdrive, skyrocketing electricity overheads.

Engineered for Wafer Fabs & Centros de dados

From preventing boron off-gassing to neutralizing acidic fumes, DTAF supplies the critical filtration matrix required for ISO Class 1-5 ambientes.

HEPA & Filtros ULPA

Utilizing boron-free PTFE and ultra-fine glass media. Achieves up to 99.99995% efficiency to eliminate sub-micron particles with zero chemical off-gassing.

Sala limpa & Sistema de Laboratório

Smart Fan Filter Units (UFF) and Laminar Hoods integrated with high-efficiency EC motors. Designed for silent, low-energy operation in massive ceiling arrays.

Filtros de alta temperatura

Sealed with specialized ceramic or silicone-free components. Engineered to provide H13/H14 particulate filtration for wafer baking and clean drying ovens.

Filtros de carbono

Advanced chemically impregnated filters designed to actively neutralize acidic, alcalino, and VOC gases, protecting delicate silicon wafers from corrosion.

Filtros Compactos V-Bank

Compact rigid design offering massive airflow capacity (up to 4000 m³/h). Essential for energy-efficient pre-filtration in data center cooling systems.

Redução de Energia

Enabled by swapping to DTAF’s low-resistance PTFE media.

We Build Cleanroom Filters in a Cleanroom

You cannot manufacture medical or semiconductor grade ULPA filters in a dusty warehouse. Esse DTAF, the entire production and assembly process occurs within our strictly monitored 100,000-class cleanroom facility.

In-House Media Engineering

We produce our own proprietary media, ensuring absolute supply chain control and custom formulation for specific chemical threats.

Independent Aerodynamic Testing

Every batch is rigorously tested in our lab for exact airflow and resistance compliance before dispatch.
