What is a Chemical Resistant Fume Arm?
Unlike a standard fume arm made of painted steel, a chemical resistant fume arm is built from materials like double anodized aluminum with a corrosion resistant hood. This material difference is critical for safety, compliance, and equipment longevity when working with aggressive chemicals.
Choosing the right fume arm is an investment in protecting your staff and your facility. These systems are a frontline defense. They work by pulling contaminated air away from the operator's breathing zone and feeding it directly into the building's main ventilation system. The effectiveness of a laboratory snorkel for chemical fumes depends on its ability to withstand the substances it is designed to capture. A standard arm would corrode and fail, creating a safety hazard.

Why Material Selection is Critical for Fume Extraction
When you work with aggressive chemicals, the material of your fume extraction arm is the core of its safety function. Standard materials, like simple painted steel, can quickly corrode and break down when exposed to acids, bases, or strong solvents. This degradation can lead to cracks and weaknesses, compromising the system's integrity.
A compromised arm can leak hazardous fumes back into the lab. This defeats its purpose and creates a significant safety risk. That is why the choice of material is non negotiable in any environment where corrosive chemicals are handled. Investing in a purpose built acid fume extraction arm prevents leaks, maintains capture efficiency, and avoids costly equipment failure.
The Science of Corrosion Resistance
Corrosion is an electrochemical process where a material reacts with its environment and gradually degrades. Certain chemicals accelerate this process. For example, strong acids can strip away protective coatings and attack the metal underneath.
The CHEM Model fume arm is built from double anodized aluminum for this reason. Anodization is a process that creates a thick, stable oxide layer on the aluminum's surface. This layer is much harder and more durable than the raw metal. The second layer gives the CHEM Model enhanced durability against a wide spectrum of chemicals, ensuring long term reliability.
Choosing the Right Model: FX75 vs. FX100
Picking the right size fume arm is critical for capturing fumes effectively. The two primary CHEM models, the FX75 and the FX100, are built for different scales of work. The main differences are their diameter and how much air they can move, measured in Cubic Feet per Minute (CFM).
The CHEM Model is a flexible double anodized fume extraction arm that can be installed on workbenches, lab counters, or mounted through ceilings. This versatility makes it suitable for many different lab layouts.

Which Model is Right For You?
The choice between the two models depends on your specific application.
- The FX75 is ideal for focused, targeted extraction. It is perfect for pulling fumes from a single piece of equipment or a small, defined workspace with low fume volume.
- The FX100, with its wider diameter, is designed for larger jobs. If you are dealing with more significant fume volumes or need to cover a wider area, the FX100 is the better choice.
Making the right choice helps you meet safety standards without over ventilating the space and wasting energy. This is the same principle behind selecting any specialized lab equipment.
