Installation and Maintenance of Snorkal Exhaust System as per the O&M guidelines.
Round the clock support
An exhaust snorkel, also known as a fume extraction snorkel or fume arm, is a flexible ducting system used to capture and remove airborne contaminants, fumes, or particulate matter from a specific area or source. It is commonly used in industrial and laboratory settings where local exhaust ventilation is required to ensure the health and safety of workers and prevent the dispersion of harmful substances into the surrounding environment.
Here are the key features and components of an exhaust snorkel:
Flexible Duct: An exhaust snorkel typically consists of a flexible duct made of durable materials, such as PVC or polyurethane. The flexibility allows the snorkel to be easily maneuvered and positioned to capture contaminants at their source.
Hood or Capture Device
: At the end of the snorkel, there is a capture device, such as a hood or nozzle, which is placed near the source of contaminants. The capture device is designed to effectively collect the fumes, gases, or particles and direct them into the ducting system.
Articulated Arm
The exhaust snorkel is often equipped with an articulated arm, which allows for easy adjustment and positioning of the capture device. The arm can be extended, retracted, and angled to reach different areas or accommodate varying work conditions.
Extraction System:
The captured contaminants are typically transported through the flexible ducting to an extraction system, which could be an industrial fan, a central ventilation system, or a dedicated fume extraction unit. The extraction system creates a negative pressure, pulling the contaminated air through the snorkel and preventing it from dispersing into the surrounding area.
Controls and Airflow Adjustment
Some exhaust snorkels may have controls or airflow adjustment features that allow users to regulate the suction power or airflow velocity. This flexibility enables users to optimize the performance of the snorkel based on the specific contaminants and working conditions.
Maintenance and Cleaning
Regular maintenance and cleaning are important to ensure the effective operation of the exhaust snorkel. This includes periodic inspections, filter replacement (if applicable), and keeping the ducting system free from blockages or obstructions.
