What type of service should I perform on my FFU?
Electrical service should be performed by a licensed electrician or authorized service technician. E. When performing any type of maintenance on the FFU, be careful to reduce as much as possible the potential for introducing the internals of the unit to dirt, dust, and debris that may be present in the unit's external environment. F.
What is the purpose of the FFU on my fan?
The FFU is designed to overcome the pressure drop of the filter only. The motor is not intended to pull air down supply ductwork, nor to experience a positive static pressure at the inlet forcing air through the fan.
What remote access options does Vava support?
VA supports remote access with two different applications 1. Citrix Access Gateway (CAG) and 2. CISCO RESCUE VPN Client. The Citrix Access Gateway is designed for users that do not have VA Government Furnished Equipment (GFE) – CAG is a good option to allow users access to general applications such as email and chat.
How do I adjust the airflow on my FFU?
Step 1: Ensure the unit and filter is properly installed. Step 2: Turn on FFU and set to desired airflow. See Airflow Setpoint section to determine initial setpoint. Step 3: Measure airflow using flow hood and compare against scheduled flow. Adjust speed controller as necessary to achieve design airflow.
How to set FFU?
If FFU is not already installed: Step 1: Set FFU with filter installed, on benchtop and set to desired airflow. See Airflow Setpoint section to determine initial setpoint. Step 2: Confirm airflow using a flow hood and adjust speed controller as required. Step 3: Ensure each supply air duct is balanced to scheduled airflow and matches FFU set point. Step 4: Turn off primary air source. Step 5: Install FFU into ceiling, connect ductwork. Step 6: Turn all FFUs on – ensure all FFUs are running before proceeding to next step. Step 7: Turn on primary air source. Step 8: Measure airflow using flow hood and compare against scheduled flow. FFU inlet static should be verified to be neutral. See table below if proper operation is not achieved.
How to balance a FFU?
If the FFU is ducted and removing the duct is not possible, follow the below instructions for balancing: Step 1: Turn off primary air source. Step 2: Install an air pressure measurement device (i.e. Pitot tube) in the duct prior to the FFU inlet. Step 3: Power up FFU and set speed controller to desired airflow. See Airflow Setpoint section to determine initial setpoint. Step 4: Power up the airflow control device. (Ductwork should have been previously balanced) Step 5: Read the inlet pressure. Step 6: Measure airflow using flow hood. Step 7: Using the table below, adjust FFU controller, or upstream airflow device as required Repeat steps 4-6 until desired airflow and inlet pressure (0.0 ± 0.05” w.g.) is achieved ..
How to store HEPA/ULPA filters?
Ensure that all HEPA/ULPA filters are stored in a clean, dry location in a vertical position, as labeled on the carton. Do not open the HEPA/ULPA filters until they are ready to be installed in the FFU units. All construction in the space should be complete, the site and upstream air should be clean so as not to unnecessarily load the filter. Ensure ductwork is balanced to scheduled flow and that both the space and ductwork is clean, free of debris, and ready for operation prior to installation of filter. To ensure fan filter units are properly balanced, read Technical Note: Design with VAV/ Constant Flow Boxes and Ducted Applicationsprior to starting installation. A minimum of two (2) people will be required to install the filters.
How to calculate voltage using a BAS signal?
Example: If using a BAS signal, to calculate appropriate starting voltage, first calculate the VDC (as shown in above example) VDC = 2.44 V Then double this value BAS Input Voltage = VDC*2 BAS Input Voltage = 2.44*2 BAS Input Voltage = 4.88V
What is a price fan filter unit?
Price Fan Filter Units (FFU) are ceiling module diffusers consisting of a fan/motor assembly and Roomside Removable (RSR), or Bench Top Replaceable (BTR) filters. The module is designed to provide unidirectional vertical airflow of filtered, clean air over a cleanroom space. Fan Filter Units (FFU) models will have three (3) stickers located on the back of the plenum. For ease of troubleshooting assistance, replacement parts, and general factory assistance, it is recommended that the order number, and model line string be used as reference. This information can be found on the Factory Label.
Is a constant flow program recommended for a fan filter?
In applications where the fan filter unit will be ducted with upstream VAV, constant flow boxes, valves, or other airflow devices that may have varying airflows, or modes, a constant flow program is not recommended.
Does Price FFU come with a speed controller?
The Price FFU will come completely assembled from the factory with the exception of the HEPA/ULPA filters, which will ship in its own carton, and the speed controller wall kits (if selected). Sample line string for Room Side Replaceable filter:
How to request remote access VA?
You may request remote access by visiting the Remote Access Self Service Portal ( only available while on VA's internal network).
What is a rescue GFE?
RESCUE GFE provides a security posture check and ensures VA data is encrypted from the end device into the VA trusted network. Prior to the device connecting and being allowed onto the VA trusted network the system is checked for multiple security baselines.
How to disable automatic server selection in VPN?
In the VPN tab of the setting screen, uncheck Enable automatic server selection. Close the settings.

Does RESCUE GFE support Windows 10?
This software is installed on all GFE laptops prior to being provided to the user. Currently RESCUE GFE supports Windows 7, Windows 8, Windows 10 and MAC OSX.
Introduction
The Raspberry Pi is one device which provides you a plethora of cool things to do in only a little cost. Today, I’m going to walk you through the purchase of items to the installation and your first program running on Raspberry Pi 2.
Windows 10 IoT Core Installation
Click on the hyperlink provided above for downloading the .iso for Windows 10 IoT Core for RPi 2.
Booting up
Now take your SD card and insert it into the micro SD card slot in your Raspberry Pi. Connect the mini USB power port and also connect your Pi to an external monitor/screen through the HDMI Port. Also plug in your network cable into the Ethernet port.
VS2015 Installation
To be able to develop apps for Windows 10 IoT Core, you need Visual Studio 2015 installed in your system.
Pushing your first application to RPi
We’re going to keep the first app very basic and simple. It’s just going to be a Hello World! Application pushed to the device and will be displayed on your external screen/monitor connected with the Pi.
Congratulations
Congratulations on successfully deploying your very first app for Windows 10 IoT Core using the Raspberry Pi. It was as easy as a breeze. There are so many things that can be done with the Pi and Windows 10 IoT Core and you can browse the samples list that Microsoft has provided.
