Protector® Echo™ Filtered Fume Hood

Labconco Corporation has combined its patented fully-featured Protector Hood design with Erlab’s GreenFumeHood (GFH) Technology to deliver a multi-use fume hood that requires no ducting. The Protector Echo delivers safety, energy savings, and adaptability to ever-changing laboratory spaces.


The demand for filtered fume hoods is increasing every year due to rising energy costs combined with safety requirements of a laboratory. The Protector Echo fulfills both of these needs using Labconco’s tried-and-true containment features alongside the GreenFumeHood* technology using Neutrodine* filtration by Erlab*. The Protector Echo is an intelligent fume hood that creates an environment where lab associates can feel safe working.

Safety benefits of the Protector Echo include controlled access to specified users via Radio Frequency Identification (RFID) cards, comprehensive sensor packages, secondary filtration, and gGuard* communication software.

Unauthorized personnel are prevented from operating or changing preferences on the fume hood. For example, the User card allows the fume hood operator to only turn on the blower and lights. When a maintenance schedule is required, there is a Maintenance card for the facilities manager to update settings on the fume hood. There is also an Administration card when a teacher or supervisor needs to change settings. While the fume hood is operated by each user, the data is collected and stored, showing who used the fume hood and at what time — a chain of custody.

The comprehensive sensor package monitors more than just a filter breakthrough. There is a temperature, acid, solvent, and laboratory air quality sensor included with the technology. This package allows the hood to be used with a broader range of chemicals than other filtered hoods. If the lab air quality sensor detects a spill inside the lab and outside the hood, it will raise an alarm.

Safety is of utmost importance, so the Echo has secondary filters located above the sensor package allowing for filter breakthrough and ensuring safe conditions within the lab. When the filter senses chemical breakthrough, an audible alert indicates that replacement filters should be ordered; however, the secondary filter allows some time between the alert sounding and the receipt of new filters. The user can continue their process without concern about chemical breakthrough since the secondary filters are identical to the primary filters.

The gGuard communication software is a powerful accessory that pairs with the Echo to provide monitoring statistics for the laboratory building management personnel. This software gives access to the following safety information and updates: usage authorization, filter usage, filter saturation detection, filter identification using the RFID tags on the filters, sash position, blower speed, pollution of the laboratory air, and the temperature inside the fume hood.

The Protector Echo Filtered Fume Hood provides a safe, energy-efficient solution for a broad range of general chemistry fume hood applications. For further information, please call 800- 821-5525 or visit
