Uses:
Allegro 9600-500 lay flat ducting is ideal for supplying fresh air to a confined space or removing fumes, smoke or foul air from a particular location. This ducting is used in temporary installations, with no requirement for permanent mounting of ducting, such as in water restoration projects and building renovations.
This lay flat ducting remains unaffected when exposed to moisture and most chemicals. They are also resistant to bacterial and fungal growth and hence, can be used in food preparation areas.
Compatible Accessories:
- Allegro 9600-500 lay flat ducting is attached to a confined space fan / blower of 16 or 20-inch diameter.
- A blower filter or filter box can also be added to the ducting for cleaning the supplied air and removing contaminants like dust and other particulate matter.
- Y duct connectors are fitted onto the ducts for distributing airflow in multiple directions.
Standards and Approvals:
Allegro 9500-500 lay flat ducting is fitted onto confined space fans & blowers that are OSHA & ANSI certified and UL & cUL listed for environmental health, user safety and efficient performance of the fans & blowers. The explosion-proof blowers further meet hazardous location requirements and are certified to CSA Standards to ensure maximum safety and quality of the blowers.
Installation:
- Allegro 9600-500 lay flat ducting is attached to confined space fans / blowers using a clamping accessory for temporary installation.
- Then, the blower power is switched on, and the ducting starts supplying / discharging air to the desired location.
- The ducting collapses without air supply and can be removed easily for using it elsewhere or when required.
Frequently Asked Questions:
Q. What other variants of Allegro 9600-500 ducting are available on Raptor Supplies?
A. We also supply Allegro 9500-500 lay flat ducting for fitting with confined space blowers & fans having a diameter of 14 inches. Raptor Supplies also takes care of your permanent installation requirements by delivering Allegro's ducting having non collapsible design.
Q. What does the CFM rating of a blower / fan signify?
A. Cubic Feet per Minute or CFM represents the amount of air that can be moved through a room when operating a blower / fan at the highest speed. In order to efficiently cool a room, the blower CFM should be chosen while considering the room space / size. CFM for blowers is a crucial measurement for determining if air can be circulated within the space quickly.
Q. Where should ventilation be directed in a confined space?
A. Air intake and exhaust equipment (forced air and / or exhaust) should be pointed at the immediate vicinity of each entry in the confined space.
Q. What is the effect of ducting on the confined space blower's output?
A. Several factors that can affect the total output of a blower. Generally, the number of bends and length of ducting attached to a blower adversely affect its output. The biggest reduction in output occurs after the first addition of ducting or bends, thereafter the drop is much smaller.
Q. Is it better to ventilate or extract air using Allegro 9600-500 lay flat ducting?
A. Lay flat ducting should be used for positive ventilation in confined spaces. They are also suitable for extracting fumes or toxic air.
Q. What are statically conductive ducting?
A. Statically conductive ducting are equipped with strong grounding wires to discharge static build-up and prevent accidental sparks in hazardous locations. They also feature a special coating for higher temperature resistance. They are generally used in locations where toxic or explosive gases generate.
Q. What is the difference between Allegro lay flat and standard ducting?
A. A lay flat ducting has collapsible design that lays flat when the airflow from a blower / fan stops. It is generally used in temporary applications that do not require permanent attachment to the blower. On the other hand, standard ducting has retractable, non-collapsible design that maintains its shape even when the airflow stops.
Q. How can users select the right variant for their needs?
A. Users can select a ducting based on the diameter of the confined space blower required. It can be determined by checking the chart of air consumption at various inlet pressures. The 'air consumed' data indicates the amount of hazardous air / fumes that a blower can consume for degassing industrial confined spaces. Another point to be noted while selecting a ducting is the total volume of the space to be ventilated.
Q. Why Allegro 9600-500 ducting is 22 inches in diameter when it fits blowers having 16 or 20 inch diameter?
A. Allegro 9600-500 lay flat ducting has a diameter of 22 inches when flat, but it can actually fit on 16 / 20 inch blowers. Its diameter increases in its flattened state as the airflow changes the ducting's shape.
Q. How does the Allegro blower ducting work?
A. Allegro 9500-500 lay flat ducting is connected with confined space blowers or fans using duct clamps or other accessories. It changes into a cylindrical shaped ventilation tubing, once the blower starts supplying air. It returns to its original shape when the blower power is switched off. This ducting can be moved from one place to another easily if required.
Q. How do I install this lay flat ducting?
A.
- This ducting is attached to confined space fans / blowers using a clamping accessory for temporary installation.
- Then, the blower power is switched on, and the ducting starts supplying / discharging air to the desired location.
- The ducting collapses without an air supply and can be removed easily for using it elsewhere or when required.
Q. How do I maintain Allegro 9600-500 lay flat ducting?
A.
- Perform regular visual inspections to check for any signs of damage, wear, or deterioration.
- Clean the ducting using a mild detergent or cleaning solution with water to remove dirt, dust, or debris.
- Rinse the ducting thoroughly with clean water to eliminate any residue from the cleaning solution.
- Allow the ducting to air dry completely before storing or reusing to prevent the growth of mould or mildew.
- Store the ducting in a clean, dry area away from direct sunlight and extreme temperatures when not in use.
- Keep the ducting away from sharp objects or surfaces that could puncture or damage it.
- Inspect the connections and attachments of the ducting to ensure they are secure and intact.
- Replace any damaged or excessively worn sections of the ducting with new ones for optimal performance and safety.
- Always follow the specific maintenance recommendations and procedures provided by the manufacturer for the Allegro 9600-500 lay flat ducting.
Q. What points should be considered while choosing a lay flat ducting?
A.
- Evaluate the compatibility of the ducting material with the intended environment and transported substances.
- Determine the required size and diameter based on airflow volume and space constraints.
- Assess the ducting's flexibility to navigate curves and bends without airflow restrictions.
- Consider the ability of the ducting material to withstand the desired temperature range and resist chemicals or corrosive substances.
- Determine if fire-resistant properties are necessary for added safety.
- Ensure the ducting can withstand the intended airflow pressure without leaks or failures.
- Consider the required length and ease of transportation if the ducting needs to be moved frequently.
- Choose a material that can withstand outdoor conditions and UV radiation without degradation.
- Check for relevant industry certifications and compliance with applicable standards.
- Consider the cost of the ducting while ensuring it meets performance and durability requirements.
