How to Clean an Electrostatic Air Filter: Step-by-Step Guide & Mistakes to Avoid
Unlike disposable fiberglass or pleated filters that end up in landfills every few months, an electrostatic air filter is designed to be washed, dried, and reinstalled for years. (If you are new to this technology, read our complete guide on what is an electrostatic air filter to understand how static attraction works). However, its greatest […]
What is an Electrostatic Air Filter
An electrostatic air filter is an air cleaning device that utilizes electrostatic attraction to capture airborne particulates. Instead of relying solely on dense, woven mechanical fibers to trap particles like a sieve, an electrostatic filter charges airborne contaminants and pulls them toward oppositely charged collection surfaces like a magnet. In today’s heating, ventilation, and air […]
Pocket Filter Selection Guide for HVAC Systems
Pocket filters are widely used in commercial HVAC systems, air handling units (AHU) and industrial ventilation systems. Their multi-pocket design provides a large filtration area within a relatively compact frame, making them a practical choice for handling substantial volumes of air. DTAF offers a range of pocket air filters for commercial and industrial HVAC applications, […]
How to Operate an FFU in a Cleanroom: A Step-by-Step Guide
A fan filter unit (ФФУ) is an important component of many cleanroom air filtration systems. It combines a fan, motor, and high-efficiency filter to deliver filtered air into a controlled environment. Correct operation helps maintain airflow, support cleanroom cleanliness requirements, and reduce unnecessary energy consumption. Whether you are setting up a new cleanroom or maintaining […]
HEPA vs Activated Carbon Filters: Differences and When to Use Both
HEPA vs activated carbon filters handle different pollutants. See real Pa budgets, carbon mass and mesh data, and how to specify both stages in one order.
When Should Commercial HVAC Activated Carbon Filters Be Replaced?
How to tell when a commercial HVAC carbon filter is spent, why pressure drop cannot prove saturation, and how to build a replacement schedule from your own log.
How to Choose Activated Carbon Filters for Commercial HVAC Systems
How to choose an activated carbon filter for HVAC systems in offices, hotels, and malls — formats, pressure drop, contact time, prefiltration, replacement.
What Does FFU Mean in HVAC? Understanding FFU Systems
In HVAC, FFU stands for Fan Filter Unit. It is a compact air filtration device that combines a fan, motor, and high-efficiency air filter in one unit. FFUs are commonly used in cleanrooms and other controlled environments where airborne particle levels need to be carefully managed. Unlike a conventional air handling unit, an FFU is […]
What Is a V-Bank Filter? Типы, Приложения, and Selection Guide
What Is a V-Bank Filter? A V-bank filter is an air filter designed with multiple V-shaped filter media sections arranged inside a single frame. This design provides a large filtration area within a relatively compact space, making it suitable for HVAC systems and air handling units (AHU) that require high airflow and efficient particle removal. […]
AC vs. EC FFU: Which Is Better for Your Cleanroom?
Choosing between an AC and an EC fan filter unit (ФФУ) affects more than the initial equipment price. Motor technology can influence energy consumption, airflow adjustment, control integration, and long-term operating costs. But is an EC FFU always the better choice? The answer depends on your cleanroom’s operating hours, required airflow, electricity rate, and control […]
