PassThru For Clean Rooms Barrier Type

DW400PTSM PassThru For Clean Rooms Barrier Type Washer-Extractor

The EDRO barrier type PassThru for Clean Rooms (DWPT_SM) washer-extractor is a specialized machine used for the prevention of cross contamination.

The exclusive "Clean Seal" system provides a physical barrier and positive air flow between the clean and soiled operating sides. The standard DynOzone Disinfecting & Sanitizing Laundry System produces a safe, disinfected, and sanitized air stream which is injected into the wash wheel to improve wash quality.

The machines also feature a state-of-the art DynaTrol HMi Touch Screen Control. The range is available in 200 (91 kg) and 400 (182 kg) pound models.

In hospitals, nursing homes, and clean rooms wherever soiled, and possibly contaminated, linen must be isolated from clean linen, PassThru for Clean Rooms washer-extractors provide the necessary safe separation.

Soiled linen is loaded into the machine from one side and clean linen is removed from the other side of the machine. Thus, cross-contamination is avoided. EDRO PassThru for Clean Rooms models feature the "Clean Seal" sealing system. Built flush against the sides of the Clean Seal, the design provides total separation of loading and unloading operations with better, easier installation. An uninterrupted flow of positive make-up air from the clean room side to the soiled room side is continually flowed through the machine while in operation, preventing airborne cross-contamination of the load.

Barrier Type PassThru for Clean Rooms washer-extractors have all the outstanding features that make EDRO washer-extractors extraordinary machines in design, construction and performance. They feature the patented "3-D" basket design which assures the ideal wash action for outstanding laundering results, while stainless steel, used for the basket, shaft and shell wrap assure long life. An interlocking door system prevents both doors from being opened at the same time. A smart control system prevents simultaneous soiled room and clean room operation of the machine. The washer's control is located on the washroom (loading) side. Forward and reverse jog controls, as well as signal and emergency stop switches are located on the unloading side.

Typical installations include hospitals, nursing homes, and clean room laundries. With the increasing demand of computer components, we have also installed machines in clean room laundries of microprocessor and semi-conductor production plants.
