4/12/2023 0 Comments Scoop duck![]() This small correction gained a customer for life. ![]() With limited space and the right conditions, a scoop takeoff solved the airflow complaint. When he took the flexible duct off the collar, he felt air shooting past the duct opening, not coming through it. The original takeoff was a straight collar about 2.5 feet downstream from a ductboard, three-piece, 90-degree elbow with no airflow going into the flexible branch duct. These takeoffs do have their place, but you need to understand their limitations.ĭaniel Vaughan, an HVAC technician, told me he solved an airflow issue using a scoop takeoff. This results in reduced airflow to the next branch duct in line. When these takeoffs are staggered in a row, there is no chance for air to straighten back out after the fitting. It takes some time for traffic to get going again once vehicles move around the lane restriction. Airflow responds the same way inside a duct system when scoops or extractor fittings are used. Think back to the traffic example, if you suddenly block off one lane of traffic all at once, you’ll have a backup. When placed into the airstream, directional takeoffs work great for the first branch duct they are connected to. While the concept looks great on paper, these fittings can cause more problems than they solve due to their field application. The idea is to grab air from the duct and direct it into the branch fitting. DIRECTIONAL TAKEOFFSĭirectional takeoffs have some form of a metal scoop or extractor fitting (turning vanes that protrude into the airstream). If you prefer round, these are a good choice to consider. It’s easier for air to change direction and enter this style of takeoff. The airflow penalty with these fittings is greatly reduced since the duct side opening is often 25-30 percent larger than the branch duct it is feeding. These provide a mix of both cost-effectiveness and increased airflow performance. PRO TIP- Send a schematic or drawing of where food trucks are to park and serve.The next progressions from round takeoffs are conical and square-to-round takeoffs. Give us the exact location of where to park and which direction to serve from. Keep in mind we need enough room for people to form a line and wait for food especially if there are multiple vendors. Restroom access is required by the health department. Let vendor staff know where restroom facilities are. Unless the event is guaranteed to have multiple hundreds of attendees, make sure that there is no overlap in menu offerings. As the host, it is your responsibility to make sure menu items don’t overlap. Make sure you let us know ahead of time what other food vendors will be at the event.ĭon’t overlap menu items. You are allowed to ask them to remove their dessert items for an event to avoid overlapping. Keep in mind that some food trucks also offer dessert options. Another guideline is to not have more than one dessert option for every 5 lunch/dinner options. Keep in mind, all vendors have a capacity of the number of items they can serve per.ġ:5 ratio of dessert vendors to meal vendors. Ratio differs based on event length, type, public vs. This ensures that each food vendor makes enough sales to make it worth their time and do better than just breaking even. A general rule of thumb is to have 1 food truck for every 250 people you’re expecting. ![]() It is important for us to be successful so we can continue to be a part of your events.ġ:250 ratio. For neighborhood events: handout flyers, make a public Facebook event, post in all relevant Facebook groups. Tag us in your promotional posts on Instagram and on Facebook. For public events, share on all socials and groups to get as much exposure and business for the food trucks.
